Description

Reforming reactor using coating device and plate coated with catalyst

The present invention comprises a plurality of combustion blocks and reforming blocks using a coating apparatus capable of coating the surface of the coating object to a desired concentration and uniform thickness and a plate coated with a catalyst by the coating apparatus, and a plurality of combustion blocks. And a reforming reactor in which reforming blocks are alternately stacked.

Referring to the background art described in Korean Patent Laid-Open Publication No. 2010-0109084, the coating process is generally coated by using a coating method such as roll coating, spray coating, slot die coating, flow coating, and dip coating. The coating liquid is applied to the surface, and the surface of the coating object is dried and cooled in a manner of drying.

The drying process in the coating process is a method of drying the coating liquid on the surface of the coating object while continuously moving the coating object in the horizontal direction in a dryer having a structure extending in the horizontal direction.

Therefore, in the case of coating on both sides of the coating object, the coating liquid is first applied to one surface of the coating object, dried and cooled, and then the coating liquid is applied to the other surface to which the coating liquid is not applied. There is a problem in that the process takes a lot of time.

In the conventional coating process, the drying process is a heat treatment process, and a boiler is provided outside the dryer, and a heat exchanger is installed inside the dryer to coat the heat medium, such as steam or air, supplied from the boiler with the heat emitted from the heat exchanger while circulating the heat medium. The method of drying the coating liquid on the surface of the object is used.

However, this coating process is a coating, cooling and drying process is performed twice, there is a problem that the efficiency of the process is low.

In addition, in order to expand the spread of small-sized (hundreds of W to kW) polymer electrolyte fuel cell power generation system, which is expected to be the most commercialized as the next-generation new energy clean environment technology, supplying hydrogen, a power generation fuel, in addition to improving stack efficiency It is essential to develop compact integrated systemization technology for high efficiency and miniaturization of fuel reformer.

A fuel reformer is a device that converts a gas such as natural gas, LPG, gasoline, methanol, etc. into catalytic gas by converting it into a reformed gas containing hydrogen, and requires high efficiency and miniaturization applicable to a domestic fuel cell. It should be possible to stably produce high concentrations of hydrogen.

Fuel reformers are classified into partial oxidation (POX), steam reformer (SR) and autothermal reformer (ATR) depending on the reforming method.

At this time, the partial oxidation reforming does not require heat supply due to the exothermic reaction, and the response characteristics are fast, but the hydrogen conversion efficiency is low, and the steam reforming reaction is usually a strong endothermic reaction and a high temperature is required to increase the hydrogen conversion rate of the fuel. .

Generally, the reaction conditions under which the catalyst is used are the reaction temperature of 700 to 850 ° C., the pressure to atmospheric pressure to 40 atmospheres, the space velocity (GHSV) of about 3,000 to 6000 hr −1, and the composition of the catalyst is a heat-resistant carrier (α-alumina or calcium aluminate). Since the reduced nickel is supported (about 10 to 12%), the surface area is 10 m 2 / g or less.

Steam reforming has a high hydrogen conversion efficiency, but because of the endothermic reaction, heat must be supplied and response characteristics are slow.

Autothermal reformer can take advantage of the partial oxidation reforming and steam reforming method, it requires less energy and has a fast response characteristics. Steam reforming is endothermic reaction and partial oxidation reaction is exothermic, so if the thermal equilibrium is maintained, The autothermal reforming reaction can proceed without supplying energy.

As a conventional technology, as shown in Korean Patent No. 10-1220120 (January 3, 2013), an inner cylinder is provided inside the main body, and an ATR catalyst layer is built in the main body and the inner cylinder, respectively, and a reactor in which a diffusion part is formed at the lower end of the inner cylinder; The upper end of the main body, the head having a power source and the first raw material injection portion is formed on the outside thereof, the tube penetrates the head up and down to couple to the upper end of the inner cylinder, and at least one line in the tube up and down A reactant communication disposed therein, a distilled water introduction portion formed at an upper portion of one side of the tube, a zig-zag plate communicating with the distilled water introduction portion and extending in a zigzag form to a lower end of the tube, and water vapor formed at any one side or both lower portions of the tube; Heat exchanger consisting of a discharge hole and a product discharge portion formed on the upper surface of the tube, wrap the tube inside the body Is attached to the outside of the partial oxidation catalyst bed, and the main body is installed on the lower side of the electric heater is receiving power from the power source, the electric heater provided a reforming unit comprising a thermocouple for detecting the internal temperature.

However, the most problematic part in the production of hydrogen by hydrocarbon reforming is the supply of heat. The reforming reaction is a high endothermic reaction and the temperature of 700 ~ 750 ℃ must be maintained for the reformation of natural gas, and diesel fuel In the case of the modification of the high temperature of 800 ℃ or more is required.

Most reformers are designed with integrated reformer and combustor for smooth supply of heat, and various types of heat exchange methods are applied. Especially, small reformer for fuel cell uses direct heat from stack flue gas and unreacted fuel in stack flue gas. The method of combustion is adopted, and it may be most preferable to directly use the heat of the hot stack flue gas through a heat exchanger, but the temperature of the reformer is 800 ° C. using the heat of the flue gas because the stack flue gas has a temperature of 800 to 850 ° C. The heat transfer efficiency may be somewhat low to maintain above.

In addition, since the flame control method is very difficult to control the temperature and the flame temperature is very high, nitrogen oxides are generated from the oxidation of nitrogen in the air used as the flame retardant to cause environmental problems.

Further, looking at the combustion block 200 in more detail, as shown in FIG. 9, the combustion block 200 generates catalytic heat by catalytically contacting fuel and air introduced into an internal space with a catalyst.

At this time, the combustion block 200 forms a space therein, and includes a frame 210 having a front and a rear open, the frame 210 according to an embodiment of the present invention is 150mm in width, 300mm in length Form a square with a thickness of 20mm.

Only the side is overheated, which is caused by the reaction of the vaporized liquid fuel with air to keep the temperature of the reactor sufficiently high.

This phenomenon is that before the fuel flows into the reactor, the fuel is combusted in the fuel gas injection pipe 211, and the heat of combustion generated by the combustion in the fuel gas injection pipe 211 is lost to the fuel gas injection pipe 211 side wall Because of this, the heat of combustion cannot be sufficiently obtained inside the combustor.

In addition, the fuel and air are heated in separate pipes, and the fuel and preheated air are separated and injected to be mixed at the inlet inside the reactor, thereby preventing overheating of the combustion gas injection pipe 211, as well as a combustion block. The temperature inside the 200 is also kept stable.

In addition, when the reforming block 300 is described in more detail, as illustrated in FIG. 9, the reforming block 300 is disposed to be interviewed with the combustion block 200, and the heat conducted from the combustion block 200 is illustrated. The fuel is reformed by contacting the catalyst with the fuel and air introduced into the internal space using the.

In this case, the reforming block 300 has a space formed therein, and includes a frame 310 in which the front and rear surfaces thereof are opened, and the frame 310 of the reforming block 300 according to an embodiment of the present invention also has The steel plate is 150mm wide, 300mm long and 20mm thick.

Here, the capacity of the reformer may be increased by increasing the thickness of the frame 310 of the reforming block 300.

One side of the frame 310 is connected to the fuel gas injection pipe 311 for inducing fuel and air to be introduced into the space of the frame 310, the other side to guide the exhaust gas generated by the combustion to the outside Connect the discharge pipe 312 to.

In addition, a pair of perforated plates 313 are disposed above and below the space of the frame 310 to disperse the fuel and air introduced into the space of the frame 310 to be evenly spread throughout the space.

At this time, it is preferable that the perforated plate 313 positioned above the pair of perforated plates 313 has a larger perforation size than the perforated plate 313 positioned below.

In addition, a plurality of reforming catalyst plates 220 are vertically disposed under the perforated plate 313 to form a channel through which fuel and air flow in the space of the frame 310.

Here, the reforming catalyst plate 220 is one of an alloy material of either Fecral (FeCrAl) or Nicral (NiCrAl) is provided in the form of a metal foam that is a fully open porous metal structure, the surface The reforming catalyst is coated by the coating apparatus 100 described above.

In addition, the catalyst plate and the reforming catalyst plate according to the present invention coat the catalyst on the surface of the metal foam with the coating apparatus described above, the reforming catalyst was loaded with rhodium on the same support, and the amount of the precious metal catalyst was about 0.02 wt%. to be.

Since the metal foam catalyst forms uniform pores, the pressure drop is small even when the flow rate of the reactant is increased, and thus the throughput per unit volume of the catalyst layer can be increased. About -1.

In addition, since a metal material is used, there is an advantage in heat transfer, and the catalyst plate and the reforming catalyst plate in the form of metal foam are filled in the channel form in the flow direction of the fluid inside the reactor, and the reforming catalyst plate is filled according to the throughput of the reforming fuel. The number of can be adjusted.

In addition, a catalyst plate and a reforming catalyst plate are fixed to the combustion block 200 and the reforming block 300 space, and a metal plate is provided to control the combustion block 200 and the reforming block 300 space. By having a heat storage effect, the combustion block 200 and the reforming block 300 may perform a buffer function against a temperature change in a space.

Looking at the embodiment of the reforming reactor according to the present invention with reference to Figures 10 to 12 as described above.

The combustion block forming the combustor of the reforming reactor 1000 according to the present invention heats the initial temperature of the hot box 1100 using an electric furnace to 270 to 350 ° C. for starting.

At this time, the temperature rise rate in the reactor was different according to the initial heating temperature of the catalytic combustion, the higher the temperature of the hot box, the faster the temperature rise rate in the reactor.

In addition, as shown in FIGS. 11 and 12, the temperature inside the reactor varies according to the amount of fuel supplied. When the space velocity is 8000, the temperature inside the combustion block converges to about 600 ° C., and the space velocity is gradually increased. When the temperature inside the reactor was also increased step by step.

Here, if the temperature inside the combustion block at about 24000 space velocity is maintained at about 980 ℃, the temperature of the reforming block 300 constituting the reformer also rose to about 750-800 ℃, reforming reaction is divided into starting conditions and operating conditions By adjusting the S / C and O2 / C ratios.

The reformer increased the temperature in the reactor to about 870 ° C. by the partial oxidation reaction at the starting condition, and maintained at about 820-850 ° C. even in the operating conditions.

At this time, the temperature of the hot box is continuously increased and converged at about 750 ° C., and the electric furnace which has already exceeded the heating conditions of the electric furnace maintains the operating state in which the heating heater is no longer operated.

The above operation was performed for about 700 hours, and stable driving conditions were maintained.
