Description

Flow synthesis column and flow synthesis equipment

The present invention relates to a flow synthesis column and a flow synthesis apparatus.

The method of synthesizing a product from a plurality of reactants is roughly classified into a method of synthesizing by batch synthesis and a method of synthesizing by flow synthesis.

When a product is synthesized from a plurality of reactants by batch synthesis, a liquid containing the plurality of reactants and a catalyst are placed in a reaction vessel. The plurality of reactants are reacted inside the reaction vessel. This produces a product and, in many cases, a by-product. When a plurality of reactants are reacted, in many cases, steam, cold water or a refrigerant is passed through the reaction vessel to heat or cool the liquid. Also, a plurality of reactants are brought into contact with the catalyst. The liquid containing the product, by-product and catalyst is discharged from the reaction kettle. Products, by-products and catalysts are separated by filtration, isolation and the like. This gives the desired product. The separated catalyst is often discarded.

When a product is synthesized from a plurality of reactants by flow synthesis, a liquid containing the plurality of reactants is allowed to flow into the flow synthesis column. Multiple reactants are reacted inside a flow synthesis column. This produces a product and, in many cases, a by-product. When a plurality of reactants are reacted, in many cases, the outer peripheral surface of the flow synthesis column is heated or cooled to heat or cool the liquid. In addition, a plurality of reactants are brought into contact with a catalyst supported on a carrier provided in a flow synthesis column. The liquid containing the product and by-product is flushed from the flow synthesis column. The product and by-product are separated by filtration, isolation, etc. This gives the desired product.

Flow synthesis has the advantage that the process of separating the catalyst can be omitted compared to batch synthesis. Further, the flow synthesis has an advantage that the waste of the catalyst can be suppressed as compared with the batch synthesis. In addition, flow synthesis has an advantage that products can be continuously produced as compared with batch synthesis. In addition, flow synthesis has the advantage that the cost of energy for heating or cooling the liquid can be suppressed as compared with batch synthesis.

In the flow synthesis column, the heat transfer in the radial direction depends on the heat transfer between the carriers and the heat transfer by the liquid. However, in many cases, heat transfer between carriers and heat transfer by liquids are not sufficient. Therefore, in the flow synthesis column, it is difficult to make the temperature distribution in the in-cylinder space uniform in the radial direction. For example, when the reaction for synthesizing a product from a plurality of reactants is an exothermic reaction or when the outer peripheral surface of the flow synthesis column is cooled, the temperature at the radial center of the in-cylinder space becomes relatively high. , The temperature of the radial peripheral part of the in-cylinder space becomes relatively low. On the contrary, when the reaction for synthesizing a product from a plurality of reactants is an endothermic reaction or when the outer peripheral surface of the flow synthesis column is heated, the temperature at the radial center of the in-cylinder space is relatively low. Therefore, the temperature of the radial peripheral portion of the in-cylinder space becomes relatively high. If the temperature distribution in the in-cylinder space cannot be made uniform in the radial direction of the flow synthesis column, the yield of the product decreases and the amount of by-product produced increases.

The present invention has been made in view of this problem. An object of the present invention is to provide a flow synthesis column capable of making the temperature distribution in the in-cylinder space uniform in the radial direction.

The present invention relates to a column for flow synthesis.

The flow synthesis column is equipped with a cylinder, a wall and a catalyst.

The cylinder has a space inside the cylinder.

The wall divides the space inside the cylinder into multiple cells extending in the axial direction of the cylinder.

The catalyst is exposed inside each of the multiple cells.

The present invention is also directed to a flow synthesis apparatus including the flow synthesis column.

According to the present invention, the wall increases the heat exchange area between the liquid and the flow synthesis column. Therefore, heat can be efficiently transferred in the radial direction via the wall.

This makes it possible to make the temperature distribution in the in-cylinder space uniform in the radial direction. As a result, the distribution of the reaction rate of the chemical reaction in the in-cylinder space can be made uniform in the radial direction.

Also, the temperature of the in-cylinder space can be brought close to the temperature suitable for the chemical reaction. As a result, the reaction rate of the chemical reaction in the in-cylinder space can be increased.

Therefore, the yield of the product can be increased. In addition, the amount of by-products produced can be suppressed.

1 1st Embodiment 1.1 Flow synthesizer FIG. 1 is a diagram schematically illustrating the flow synthesizer of the 1st embodiment.

As shown in FIG. 1, the flow synthesizer 1 of the first embodiment includes a mixer 11, a flow synthesis column 12, and a temperature controller 13.

The mixer 11 mixes a plurality of reactants 21 to produce a liquid 22 containing the plurality of reactants 21. Further, the mixer 11 causes the generated liquid 22 to flow into the flow synthesis column 12. In the first embodiment, the plurality of reactants 21 are three kinds of raw materials A, B and C. The plurality of reactants 21 may be two kinds of raw materials or four or more kinds of raw materials. The liquid 22 may contain a plurality of substances other than the reactants 21. For example, the liquid 22 may contain a solvent.

The flow synthesis column 12 synthesizes the product 23 by reacting a plurality of reactants 21 contained in the inflowing liquid 22 with each other. The flow synthesis column 12 drains the liquid containing the synthesized product 23.

The temperature controller 13 adjusts the temperature of the flow synthesis column 12. As a result, the temperature of the liquid 22 flowing into the flow synthesis column 12 is adjusted to a temperature suitable for a chemical reaction in which a plurality of reactants 21 are reacted to synthesize the product 23. The temperature controller 13 has at least one function of a heater for heating the flow synthesis column 12 and a cooler for cooling the flow synthesis column 12. The heater is an electric resistance heater that performs electric heating, a heat medium heater that circulates a heat medium such as steam or oil, and heats the heat medium. The cooler is an electronic cooling cooler that performs electronic cooling by utilizing the Pertier effect, a cooler that circulates cold water or a refrigerant to perform cooling, and the like.

1.2 Flow Synthesis Column FIG. 2 is a perspective view schematically illustrating the flow synthesis column of the first embodiment. FIG. 3 is a cross-sectional view schematically showing the flow synthesis column of the first embodiment. FIG. 4 is a vertical cross-sectional view schematically showing the flow synthesis column of the first embodiment.

As shown in FIGS. 2, 3 and 4, the flow synthesis column 12 includes a cylinder 31. As shown in FIGS. 3 and 4, the cylinder 31 has an in-cylinder space 41. In the first embodiment, the cylinder 31 is a cylinder. Further, the in-cylinder space 41 is an in-cylinder space. The cylinder 31 may be a cylinder other than a cylinder. Further, the in-cylinder space 41 may be an in-cylinder space other than the in-cylinder space. For example, the cylinder 31 may be a square cylinder. Further, the in-cylinder space 41 may be a square in-cylinder space. The temperature of the outer peripheral surface 31a of the cylinder 31 is adjusted by the temperature controller 13.

As shown in FIGS. 3 and 4, the flow synthesis column 12 includes a wall 32.

The wall 32 divides the in-cylinder space 41 into a plurality of cells 42. The plurality of cells 42 extend in the axial direction DZ of the cylinder 31. The plurality of cells 42 are arranged in a direction perpendicular to the axial direction DZ. The plurality of cells 42 are preferably evenly arranged. As a result, it is possible to prevent the flow of the liquid 22 from being obstructed when the liquid 22 is poured into each of the plurality of cells 42. This makes it possible to reduce the pressure loss when the liquid 22 is poured into each of the plurality of cells 42. In the first embodiment, the wall 32 divides the in-cylinder space 41 in a grid pattern. The wall 32 may partition the in-cylinder space 41 in a non-grid pattern. For example, the wall 32 may partition the in-cylinder space 41 in a honeycomb shape. The wall 32 is continuous from the cylinder 31.

As shown in FIGS. 3 and 4, the flow synthesis column 12 includes a catalyst 33 and a carrier 34.

The catalyst 33 is exposed inside each of the plurality of cells 42. The catalyst 33 is a catalyst that accelerates the reaction rate of a chemical reaction in which a plurality of reactants 21 are reacted to synthesize a product 23. In the first embodiment, the catalyst 33 is supported on the surface of the carrier 34 inside each of the plurality of cells 42.

The carrier 34 is arranged inside each of the plurality of cells 42. The carrier 34 carries the catalyst 33. The carrier 34 has a spherical shape. The carrier 34 is made of silica, polymer, alumina or the like.

The liquid 22 is made to flow into the inflow port which is one end of the in-cylinder space 41. The inflowed liquid 22 is flowed into the in-cylinder space 41. The flowed liquid 22 is discharged from the outlet which is the other end of the in-cylinder space 41. When the liquid 22 is flowed into the in-cylinder space 41, it is flowed into each of the plurality of cells 42. As a result, the liquid 22 comes into contact with the catalyst 33 arranged inside each of the plurality of cells 42. As a result, the reaction rate of the above-mentioned chemical reaction becomes faster.

1.3 Advantages of partitioning the in-cylinder space by the wall When the in-cylinder space 41 is partitioned by the wall 32, the heat exchange area between the liquid 22 and the flow synthesis column 12 becomes large. Therefore, heat H can be efficiently transferred to the radial DR of the cylinder 31 via the wall 32. For example, when the above-mentioned chemical reaction is an exothermic reaction or when the temperature controller 13 cools the outer peripheral surface 31a of the cylinder 31, the radial center portion of the cylinder space 41 is moved to the radial peripheral portion of the cylinder space 41. Heat H can be efficiently transferred toward the direction. Further, when the above-mentioned chemical reaction is an endothermic reaction or when the temperature controller 13 heats the outer peripheral surface 31a of the cylinder 31, the radial peripheral portion of the tubular space 41 is moved to the radial central portion of the tubular space 41. Heat H can be efficiently transferred toward the surface. Therefore, the wall 32 can function as a good thermalization structure, and the flow synthesis column 12 can function as a good heat exchanger.

Thereby, the temperature distribution of the in-cylinder space 41 can be made uniform in the radial DR. Thereby, the distribution of the reaction rate of the chemical reaction in the in-cylinder space 41 can be made uniform in the radial DR.

Further, the temperature of the in-cylinder space 41 can be brought close to the temperature suitable for the above-mentioned chemical reaction. Thereby, the reaction rate of the above-mentioned chemical reaction can be increased.

Therefore, the yield of product 23 can be increased. In addition, the amount of by-products produced can be suppressed.

The wall 32 has physical characteristics and mechanical properties suitable for exerting this advantage. The wall 32 is preferably made of a material having a high heat transfer coefficient and a low specific heat from the viewpoint of physical characteristics. Further, from the viewpoint of mechanical properties, the wall 32 has a structure having a wide heat exchange area without obstructing the flow of the liquid 22 and increasing the pressure loss when the liquid 22 flows through each of the plurality of cells 42. It is made of a material that has high corrosion resistance. The wall 32 is made of, for example, ceramics. Ceramics are silicon carbide, alumina, aluminum nitride and the like.

1.4 Advantages of Placing the Carrier Carrying the Catalyst Inside the Cell When the carrier 34 is placed inside each of the plurality of cells 42, the liquid 22 hits the carrier 34 and the flow of the liquid 22 is slowed down. Therefore, the contact time between the plurality of reactants 21 and the catalyst 33 can be lengthened. Thereby, the above-mentioned chemical reaction can be further advanced.

Further, when the carrier 34 is arranged inside each of the plurality of cells 42, the liquid 22 flows between the carriers 34 and the flow of the liquid 22 is disturbed. Therefore, the chance of contact between the plurality of reactants 21 and the catalyst 33 can be increased. Thereby, the above-mentioned chemical reaction can be further advanced.

Further, when the carrier 34 carrying the catalyst 33 is arranged inside each of the plurality of cells 42, the specific surface area of the catalyst 33 becomes large. Therefore, the chance of contact between the plurality of reactants 21 and the catalyst 33 can be increased. Thereby, the above-mentioned chemical reaction can be further advanced.

Further, when the in-cylinder space 41 is partitioned by the wall 32 and the carrier 34 is arranged inside each of the plurality of cells 42, the liquid 22 flows between the carriers 34 and the flow of the liquid 22 is disturbed. Therefore, the chance of contact between the liquid 22 and the wall 32 can be increased. Therefore, the frequency of heat exchange between the liquid 22 and the wall 32 can be increased. As a result, heat can be efficiently transferred to the radial DR via the wall 32.

When the catalyst 33 is exposed inside each of the plurality of cells 42, the catalyst 33 can be cleaned by flowing a cleaning agent such as nitric acid or hydrochloric acid into each of the plurality of cells 42. Therefore, it is possible to suppress the disposal of the catalyst 33.

1.5 Temperature control by the temperature controller The temperature controller 13 makes the temperature distribution on the outer peripheral surface 31a of the cylinder 31 uniform in the axial direction DZ.

The temperature controller 13 may make the temperature distribution on the outer peripheral surface 31a of the cylinder 31 uneven in the axial direction DZ. For example, the temperature controller 13 has a temperature T1 on the outer peripheral surface 31a of the cylinder 31 at the position P1 in the axial direction DZ, a temperature T2 on the outer peripheral surface 31a of the cylinder 31 at the position P2 in the axial direction DZ, and a cylinder at the position P3 in the axial direction DZ. The temperatures T3 of the outer peripheral surface 31a of 31 may be different from each other.

FIG. 5 shows changes in the concentrations of raw material A, raw material B, raw material C, and product depending on the distance from the inflow port in the flow synthesis column of the first embodiment.

The progress of the chemical reaction for synthesizing the product 23 by reacting the raw material A, the raw material B, and the raw material C increases as the distance from the inflow port increases. Therefore, as shown in FIG. 5, the concentrations of the raw materials A, B, and C decrease as the distance from the inflow port increases. Further, as shown in FIG. 5, the concentration of the product 23 increases as the distance from the inflow port increases. Further, the heat generation or endothermic due to the above-mentioned chemical reaction becomes smaller as the distance from the inflow port increases. Therefore, the temperature of the outer peripheral surface 31a of the cylinder 31 suitable for advancing the above-mentioned chemical reaction changes according to the distance from the inflow port. Therefore, when the temperature distribution of the outer peripheral surface 31a of the cylinder 31 is made non-uniform, the temperature of the outer peripheral surface 31a of the cylinder 31 becomes a temperature suitable for advancing the above-mentioned chemical reaction. The temperature of the outer peripheral surface 31a of the cylinder 31 is adjusted in this way.

1.6 Deformation Example FIG. 6 is a vertical cross-sectional view schematically showing a flow synthesis column of the first modification of the first embodiment.

It is not provided in the second section S2 in the axial direction DZ. As a result, the liquids 22 flowed into the plurality of cells 42 in the first section S1 are mixed and stirred in the second section S2 following the first section S1. Thereby, the above-mentioned chemical reaction can be further advanced. Further, the concentration difference caused by the minute reaction rate difference in the plurality of cells 42 caused by the temperature difference inside the plurality of cells 42 can be eliminated, and the yield can be further improved.
