- the invention can be used in the oil refining and petrochemical industries for compounding straight-run gasolines with the obtained high-octane KAU, as well as for the production of individual aromatic hydrocarbons (benzene, toluene, xylenes) extracted during the rectification of KAU and which are widely used solvents and reagents to produce more complex organic substances, for example cumene.
- aromatic hydrocarbons benzene, toluene, xylenes
- the carrier of thermal energy necessary for the implementation of the reaction of formation of aromatic hydrocarbons is raw materials.
- the problem of energy supply of the endothermic aromatization reaction of paraffin hydrocarbons is solved by the direct introduction of oxygenates (aliphatic alcohols ⁇ 1- ⁇ 3) into the reaction zone, during the dehydration of which heat energy is released, which is necessary to ensure a high degree of conversion of the c / in feed to aromatic hydrocarbons (ArU).
- RF patent N ° 2377230 describes a method for aromatizing light alkanes containing from one to four carbon atoms, which consists in contacting the gas feed with a Pt / ZSM-5 catalyst containing platinum deposited on an MFI zeolite, the lattice of which consists of aluminum, silicon and oxygen .
- the use of this catalyst in the process of aromatization of alkanes inhibits the formation of methane and increases the selectivity for the benzene-toluene-xylene fraction (BTK).
- BTK benzene-toluene-xylene fraction
- the high ethane content relative to the amount of methane in the light gas fraction allows the use of exhaust gas as a raw material for the cracking unit.
- RF patent N ° 2163623 low-octane straight-run gasoline fractions are reformed in the presence of mono- or dihydric alcohols, taken in an amount of 0.2-5.0 mass. %
- the catalyst of the process is a mechanical mixture of two catalysts - a zeolite-containing catalyst and aluminum cobalt (nickel) - a molybdenum oxide catalyst. The process is carried out at 460-510 ° C and a volumetric feed rate of 0.3-0.9 h. "1.
- cycloalkanes and alkanes are aromatized by contacting the hydrocarbon components with an aluminum-platinum-rhenium catalyst at a mass feed rate based on the catalyst mass of 4-8 hours "1 and a temperature of 460-480 ° ⁇ , at the second stage, arenes, cycloalkanes and alkanes are hydroisomerized on zirconosulfate catalyst comprising platinum at a weight hourly space velocity based on the catalyst weight at least 8 hour, "1 and a temperature of 150-200 ° C and in the third step is carried out again aromatization cycloalkanes n alyumoplatinorenievom catalyst at a weight hourly space velocity as not less than 8 hour, "1 and a temperature of 360-400 ° C, while the pressure in the reforming reactor system inlet is 1 to 5 MPa, and a hydrogen-containing gas is supplied to the input of the reactor system in an amount corresponding to the molar ratio hydrogen / raw materials
- RF patent N223071 17 describes a method for producing an aromatization catalyst and a method for aromatizing alkanes having from two to six carbon atoms in a molecule.
- a method for the aromatization of hydrocarbons is described, which comprises: a) contacting an alkane containing from 2 to 6 carbon atoms in a molecule with at least one catalyst containing aluminum-silicon-germanium zeolite on which platinum is deposited; and b) isolate the aromatization product.
- a method for the synthesis of aluminum-silicon-germanium-platinum zeolite catalyst is described, which consists in the following stages: 1) a zeolite containing aluminum, silicon and germanium is obtained; 2) platinum is deposited on microporous aluminum-silicon-germanium zeolite; and 3) calcining the zeolite.
- a method for pretreating a catalyst for aromatization of hydrocarbons is also described, which consists of the following stages: 1) platinum is deposited on aluminum-silicon-germanium zeolite; 2) the catalyst is further treated with hydrogen and further sulfur compound; and 3) the catalyst is treated a second time with hydrogen.
- the technical effect is increased catalyst stability.
- a significant drawback of this and other traditional methods of aromatization (reforming) is the low yield of Ar and the use of noble metals in the catalysts.
- RF patent NQ2372988 describes a catalyst for the conversion of aliphatic hydrocarbons C 2 -Ci 2 and / or aliphatic oxygen-containing compounds C1-C12 into high-octane gasoline or aromatic hydrocarbons, including a pentasil type zeolite, zinc aromatization promoter and a binder.
- the specified zeolite is characterized by a molar ratio of SiO 2 / A 2 O3 in the range of 20-80 with a residual content of sodium ions of less than 0.1%
- the aromatization promoter is introduced by any of the known methods in the following ratio of components: zeolite - 30.0-90.0 wt. .%; zinc - 0.5-8.0 wt.%; the binder is the rest, while the catalyst is additionally treated with a solution of ammonium fluoride after zinc is introduced into it.
- the technical effect is the creation of a highly active and stable catalyst that provides the processing of a wide range of hydrocarbon-containing raw materials.
- the disadvantage of this catalyst is the rapid decline in its activity and, as a consequence, the need for frequent oxidative regeneration of the catalyst.
- An analogue of the developed method is RF patent N22440189, which describes a similar catalyst for the production of high-octane gasolines with a low content of benzene and durene, in which an increase in the octane characteristics of the final gasoline is achieved during aromatization of paraffinic y / v in the feedstock to obtain a high-octane aromatic y / w fraction ( FAA).
- a method for producing high octane gasolines with a high (up to 50% May.) Aromatics content is also described.
- the catalyst is heated in an isothermal reactor with heat pipes to a temperature of 280-320 ° C, and the process of contacting the raw material with a catalyst heated in isothermal a reactor with heat pipes, is carried out at a pressure of 0.1-1 MPa when feeding into the reactor raw materials with a volumetric feed rate of 1-5 hours "1 (by liquid) and inert gas at a volumetric feed rate of inert gas of 1000-10000 h " 1 after evaporation raw materials in the preheater.
- a significant disadvantage of the proposed method is that for the subsequent production of individual ARUs (benzene, toluene, xylenes) from gasoline with an ARU content of not higher than 50.2%, a rather complicated extraction rectification is required, since the composition of the FAA contains aliphatic UV.
- RF patent N22277524 The closest analogue of the developed invention is RF patent N22277524, which characterizes a method for producing aromatic hydrocarbons from hydrocarbon raw materials containing aliphatic hydrocarbons.
- the aromatization method involves the conversion of raw materials (propane-butane fraction containing 0.8 wt.% Ethane, 14.0 wt.% Propane, 1.5 wt.% Iso-butane and 80.6 wt.% N-butane and 3, 1 wt.% Pentane) upon its contact with a catalyst located in two zones differing in the conditions for the conversion of aliphatic hydrocarbons into aromatic ones, and to isolate C 5+ hydrocarbons (KAU) containing aromatic hydrocarbons from the resulting products, the feed is sent to the low-temperature conversion zone for more active aliphatic hydrocarbons, from the resulting product I isolate hydrocarbon stream Cs +, and the remaining product hydrocarbons low temperature zone is directed into the high conversion area less active aliphatic hydrocarbons.
- raw materials propane-butane fraction containing 0.8 wt.% Ethane, 14.0 wt.% Propane, 1.5 wt.% Iso-butane and 8
- KAU The output of KAU in one pass of raw materials does not exceed 38.4%, while the xylene content in KAU is 21.8%.
- KAU When using the recirculation of separation gases (in stream 13) with a yield of 52.6% for raw materials, KAU with a total aromatic content of 94.1% (benzene 14.1%, toluene 45.3%, xylenes 23.0%, C 9 + 10.7%).
- the disadvantage of the proposed method is the very high temperature of the raw materials in the recovery heat exchangers and furnaces (up to 575 ° C), which leads to coking of the heat exchangers, as well as the high temperature of the process (520-550 ° C). It should also be noted the complex instrumentation of the process, since in 2 reaction zones (reactors) high pressure is used (0.8- 2.0 MPa), as well as recirculation of separation gases. In addition, without the use of gas recirculation for raw materials containing 85 wt.% C 4+ hydrocarbons , a low yield of ArU is observed.
- the technical problem solved by the present invention is to create a highly effective catalyst for the aromatization of raw materials and aliphatic alcohols, providing an increased yield of ARP in the resulting KAU, as well as to develop a simpler and less energy-intensive method of aromatization of C 3 -C gases, light low-octane hydrocarbon fractions in mixtures with aliphatic alcohols Ci-Cz, characterized by a high content of highly demanded xylenes.
- the technical result obtained by the implementation of the present invention consists in achieving a higher yield of ARP with almost complete conversion of the feed of oxygen and oxygenates, increased selectivity for the formation of xylenes in the composition of KAU, while simplifying the technological design of the process by using a lower (in .h., atmospheric) pressure.
- a binder preferably silicon oxide, possibly with the addition of alumina in an amount of up to 25 wt.% by weight of the binder
- Pretreatment with alkali and modification of zeolites with magnesium and REE oxides was carried out at room temperature during the impregnation of zeolites (in terms of moisture capacity) with aqueous solutions of alkali (NaOH), magnesium nitrates or REE.
- non-acidic silica as a binder for the catalyst compared to that used in the prototype invention of alumina distinguishes the catalyst by significantly lower activity in cracking reactions and leads to greater selectivity for AR.
- the catalyst has greater mechanical strength when operating at high temperatures in the presence of reaction water.
- a distinctive feature of the proposed method of aromatization is also a wider range of UV raw materials, which can be used as a mixture of paraffin and olefin C 3 -C 4 gases, BFLH, various gasolines (n.k-200 ° C) and oxygenates, as well as mixtures u / in with oxygenates (aliphatic alcohols With 3 With the content of oxygenates from 10 to 50% vol.
- KAU can be used to obtain individual ARUs (including demanded xylenes) with their further use in chemical synthesis processes.

- Example 10 (comparative). The process was carried out as in example 3, except that the process was carried out at a temperature of 520 ° C and a pressure of 8 atm (as in the invention of the prototype), and PBP without additives of oxygenate (methanol) was used as a raw material.
- TOTAL 100 100 100 100 100 100 100 100 100
- composition of KAU,% of May including:
- the KAU yield is calculated on the u / in part of the feed (as an example, in the methanol molecule - ⁇ the hydrocarbon part is - ⁇ , litis, fran it is 43.8 wt.%).
- the technical result obtained by the implementation of the invention consists in achieving an increased yield of KAU (in one pass of raw materials without recirculation of separation gases) and selectivity for xylenes.
- the indicators of the aromatization reaction of PBP according to the proposed method (example N26) with the addition of oxygenate (methanol) to the raw materials and the prototype (comparative example N Q 10, without additives of oxygenates)
- the catalyst of the present invention lower temperature (500 instead of 520 ° ⁇ ) and pressure (6 instead of 8 atm)
- a higher yield of KAU in one pass of raw material is achieved (38, 1% versus 29.2%).
- the concentration of the aromatic fraction of Ce in the composition of KAU is up to 41.6%
- the example of Ns10 its concentration does not exceed 22.7%.
- a significant result of the present invention is that as a result of mixing gaseous gaseous hydrocarbon feed with oxygenates, there is no need to preheat it to temperatures of about 550-575 ° C, as is done in the prototype invention during aromatization of PBP, since it is released during the conversion of oxygenates additional heat required for the aromatization reaction.
- the raw material flows at the inlet to the reactor should be heated only to 150-250 ° C, and this can be ensured by the recovery of heat from the hot gas stream of the product at the outlet of the reactor, which eliminates the use of multi-section furnaces (fire heaters).
