Description

The present invention relates to a method for producing hydrocarbons from dimethyl ether (a synthesis gas conversion product, one of the sources of which is associated petroleum gas), in particular, a mixture of hydrocarbons of a gasoline series with a low content of aromatic compounds, which is similar in composition to a gas condensate.

Currently, associated petroleum gas (APG) in the fields is mostly flared (more than 20%) and only partially used. Effective methods of chemical processing of associated petroleum gas, implemented on an industrial scale directly in the fields, are practically absent.

The use of associated gas as a chemical feedstock is hindered mainly by the fact that a significant part of the associated gas is produced at small deposits that are remote from traditional processing centers. In such fields, they try not to mess with the creation of infrastructure for the collection, compression, transportation and processing of associated gas, since this requires significant energy, capital and operating costs, as well as additional energy costs for the compression of associated gas. In addition, it is well known that GTL synthesis (gas to liquid conversion) is better than purification. In synthesized products, it is much easier to control the level of impurities. This means that, in principle, they are much cleaner than petroleum products produced in the traditional way.

A feasible way to solve the problem of APG utilization is to use modular multi-purpose plants for APG processing using GTL technology to produce a variety of organic products: Fischer-Tropsch synthetic oil for pumping into the pipeline, motor fuels (e.g. gasoline, diesel fuel, etc.) and other chemical products (e.g. methanol).

However, the orientation of the APG processing scheme to the production of methanol or high-octane gasoline is possible only if the developed network of target consumers does not resolve the issue of building a pipeline or organizing transport. According to the Fisher-Tropsch APG processing scheme, a wide hydrocarbon fraction is obtained, including both aliphatic compounds and unsaturated and oxygen-containing hydrocarbons, which makes it impossible to use it as gas condensate without additional processing.

For this reason, one of the most attractive solutions to the problem of APG utilization is its processing using GTL technology from gas mixtures containing DME into a mixture of gasoline hydrocarbons with a low content (less than 5 wt.%) Of aromatic compounds - an analogue of gas condensate. The return of the condensate thus obtained into the oil pipeline will increase the degree of beneficial use of the oil well.

All known methods for producing gasoline hydrocarbons from gas mixtures containing DME are aimed at producing high-octane gasoline components with a high content of aromatic hydrocarbons.

These methods can be divided into two groups:

- two-stage methods for producing hydrocarbons from synthesis gas through DME and / or methanol with the release of an intermediate product, which are described in patents RU 2143417, WO 2006/126913 A2, RU 2226524, or without isolation of an intermediate product, as, for example, in US patent No. No. 4,481,305, 4,520,216;

- one-stage processes in which the stage of synthesis of the intermediate product and the stage of synthesis of hydrocarbons are carried out in one reactor.

The raw material for producing hydrocarbons according to the listed patents is synthesis gas, and each patent uses a specific composition of synthesis gas, which does not always correspond to those compositions that can be obtained by known processes for its production. To achieve the desired result, circulation of gas flows is used.

However, a common drawback of the technical solutions described in these patents is the high content of aromatic hydrocarbons - more than 20 wt.%.

The technical result is similar to the one-stage method for producing hydrocarbons described in patent RU 2175960. The raw material for the process is synthesis gas of composition H ₂ - 68; CO - 28; CO ₂ - 3; CH ₄ - 1 vol.% On the catalyst, consisting of zeolite type ZSM-5 (with SiO ₂ / Al ₂ O ₃ = 70) and a metal oxide component containing ZnO, Cr ₂ O ₃ and W ₂ O ₅ . The process is carried out under rather severe conditions (temperature 360-420 ° C, pressure 8-10 MPa and high volumetric feed rates 200-5000 h ^-1 ). To achieve a technical result, gas circulation is used with a multiplicity of 70-1000 of the volume of circulating gas per volume of the source gas (vol./vol.).

The result is a product with aromatic compounds up to 30.0 wt.%. A lower aromatic hydrocarbon content of 2.7 wt.% Was obtained by the authors during the semi-industrial process using a shelf adiabatic reactor with cold gas flows between the shelves by the same technical solution. In this case, the yield of liquid hydrocarbons is significantly reduced.

Another disadvantage of this process is the problem of heat removal in the reaction zone, because the preparation of C ₅₊ hydrocarbons goes through the steps of producing methanol and / or DME. During the formation of DME, heat is generated from the synthesis gas (70 kcal / mol). The same amount of heat is generated during the formation of gasoline from oxygenates. When combining these two processes in one reactor, the problem of removing the heat of the reaction arises, which can be solved by using high multiplicity of circulation. However, the process with a high circulation ratio (up to 1000 vol./about.) Complicates the stage of separation of gasoline from a very dilute mixture and complicates the implementation of this process on an industrial scale.

A known method of producing a mixture of liquid hydrocarbons enriched in isoparaffins from DME in a two-stage process.

A known method of producing high-octane components of motor gasolines from a highly diluted gas mixture containing DME in an amount of 3.2 wt.%, Described in patent RU No. 2160160 C1, B01J 29/40.

According to this invention, a crystalline aluminosilicate of the pentasil type with a ratio of SiO ₂ / Al ₂ O ₃ = 25-100, containing (wt.%) 0.05-0.1 sodium oxide, 0.5-3.0 zinc oxide, is used as a catalyst , rare earth oxides (REE) in an amount of 0.1-5.0 and a binder component. The zeolites used in the composition of the indicated catalyst are obtained by direct synthesis or by exchanging the initial Na-form of the zeolite for an H ⁺ or NH ⁺ ₄ form. As a binder component can be used synthetic aluminosilicates, alumina. To modify zeolites, an REE nitrate industrial concentrate containing 200 g of REE oxides was used as a source of REE. The resulting catalyst is preliminarily subjected to activation in an air stream at 540-560 ° C. Then a mixture of the following composition (wt.%) Is passed over the catalyst: N ₂ - 66.0, CO - 12.0, CO ₂ - 3.3, H ₂ - 15.5, DME - 3.2 at a temperature of 250- 400 ° C, a pressure of 0.1-10 MPa and a volumetric feed rate of gas raw materials of 250-1100 h ^-1 According to the prototype, the following hydrocarbon products (wt.% In a mixture of hydrocarbons) are obtained as a result of the catalytic conversion of DME (98-100%): C ₁ -C ₄ - 7.6-16.6, n-paraffins C ₅₊ - 2.1-3.2, isoparaffins C ₅₊ - 31.1-34.3, other C ₅₊ - 20.8- 40.0, aromatic C ₆₊ - 15.6-28.8.

The disadvantage of the described method is the relatively low content of isoparaffins: in the liquid products of the process, it does not exceed 34 wt.%.

Closest to the claimed technical solution are:

a catalyst for the synthesis of liquid hydrocarbons from dimethyl ether, described in patent RU No. 2248341 C1, C07C 1/20, B01J 29/44, publ. 03/20/2005, based on a crystalline aluminosilicate of the type of pentasils with SiO ₂ / Al ₂ O ₃ = 25-100, containing 0.05-0.1 wt.% Sodium oxide, zinc oxide, palladium and a binder, in the following ratio of components wt.%: ZnO - 0.1-3.0; palladium 0.1-1; crystalline aluminosilicate - 50-70 and a binder, which allows to obtain high-octane components of motor fuels from gases containing dimethyl ether;

The method of preparation of the catalyst, carried out by modifying zeolites such as pentasils with SiO ₂ / Al ₂ O ₃ = 25-100, containing 0.05-0.1 wt.% sodium oxide, 0.1-3 wt.% zinc oxide and mixing with a binder, moreover, zinc modification is carried out by the method of residual impregnation of a zeolite or a binder or by the method of zeolite ion exchange before mixing it with a binder from an aqueous solution of zinc nitrate in an amount providing a zinc oxide content in the catalyst of 0.1-3 wt.%, and then palladium is introduced by the method residual impregnation providing soda . Zhanie palladium in the catalyst is 0.1-1% by weight;

The method of producing environmentally friendly gasoline or its components with an octane rating of 92-93 according to the research method from raw materials containing up to 15 wt.%. DME and water vapor in a molar ratio of 2≥H ₂ O / DME> 0 in the presence of the described catalyst, and the feed is fed into the reactor with a space velocity of 1000-4000 h ^-1 . The presence in the feed of various amounts of hydrogen, carbon oxides, nitrogen, methane, methyl alcohol. Their content depends on the composition of the initial synthesis gas and the synthesis mode of DME.

The disadvantage of this method and the catalyst for its implementation is the high content of aromatic hydrocarbons - up to 30 wt.% And low productivity of the process. In this case, it does not exceed 30 g / m ^{3 of} synthesis gas.

The objective of the proposed technical solution is to develop a method for the synthesis of a mixture of hydrocarbons of a gasoline series with a low content of aromatic compounds from raw materials containing dimethyl ether and synthesis gas (CO, CO ₂ and H ₂ ), similar in composition to gas condensate and suitable, depending on certain tasks for injection into an oil pipeline to increase the profitability and productivity of an oil well or into a main pipeline, with the aim of transporting it to production facilities, as well as in developing a catalyst and to conduct such a process and the method of its production.

The problem is solved in that a catalyst is proposed for the synthesis of a mixture of hydrocarbons with a low content of aromatic hydrocarbons based on crystalline aluminosilicate - a zeolite of the pentasil type with SiO ₂ / Al ₂ O ₃ = 25-100, containing not more than 0.1 wt.% Sodium oxide, oxide zinc, palladium and a binder, which additionally contains zirconium oxide and / or lanthanum oxide in the following ratios of components, wt.%:

zinc oxide - 0.5-2.0 zirconium oxide - 0.2-1.0 and / or lanthanum oxide - 0.2-1.0 palladium - 0.1-1.0 6 specified zeolite - 65.0 binder - the rest.

The problem is also solved by the fact that the proposed method for producing the described catalyst for the synthesis of mixtures of hydrocarbons with a low content of aromatic hydrocarbons, including the modification of a zeolite of the pentasil type with SiO ₂ / Al ₂ O ₃ = 25-100, containing not more than 0.1 wt.% Sodium oxide , zinc oxide and palladium, mixing with a binder, molding the extrudates, drying and calcining, in which the ammonium form of the zeolite is first modified with aqueous solutions of lanthanum nitrate and / or zirconium nitrate, taken in quantities that provide soda burning in the finished catalyst zirconium oxide 0.2-1.0 wt.% and / or lanthanum oxide 0.2-1.0 wt.%, the modified zeolite is dried and calcined, after which an aqueous solution of nitrate is introduced into the zeolite under ion exchange conditions zinc, taken in an amount providing the content of zinc oxide in the finished catalyst, equal to 0.5-2.0 wt.%, add a binder and prepare the extrudates, which are again dried and calcined, then the extrudates of the catalyst are impregnated with an aqueous solution of palladium chloride, taken in an amount providing palladium in ready ohm catalyst, equal to 0.1-1.0 wt.%, and again dried and calcined to form oxides of the corresponding metals.

The problem is also solved by the fact that the proposed method for the synthesis of a mixture of hydrocarbons from gases containing dimethyl ether, synthesis gas (CO, CO ₂ and H ₂ ) in the presence of a catalyst, the process being carried out in a circulating mode with a circulation rate of 10-35, as gas mixtures use a gas mixture with a hydrogen content of not less than 71 vol% in the used synthesis gas, and the catalyst described above as a catalyst.

The technical result from the use of the proposed technical solution is:

- obtaining a mixture of gasoline hydrocarbons with a low content of aromatic compounds equal to not more than 8.0 wt.%, including durene - not more than 0.7 wt.%, which is similar in composition to gas condensate;

- increasing the productivity of the process up to 120 g / m ³ synthesis gas compared with 30 g / m ³ synthesis gas according to the prototype.

An additional technical result is an increase in the service life of the catalyst (at least a month of operation without regeneration).

When using the proposed catalyst in the process of producing hydrocarbons from synthesis gas, a mixture of hydrocarbons with a low content of aromatic compounds is obtained in high yield.

The proposed technology is promising for application at production sites and is an original and economical solution to the acute problem of today - the problem of APG utilization and is intended, first of all, to eliminate flares and reduce the dependence of oil fields on the import of methanol and other petroleum products through the disposal and processing of valuable hydrocarbon raw materials contained in APG.

The proposed technical solution at the same time allows solving environmental problems associated with the utilization of APG by burning them. Thus, through the elimination of flares, a reserve for sales of quotas for CO ₂ emissions established by the Kyoto Protocol ratified by Russia can be created. Estimates show that this can bring 400 million euros / year (14 billion rubles / year).
