摘要： The present inventors have surprisingly discovered that paraxylene selectivity is found to increase as the amount of coke on catalyst increases. In embodiments the paraxylene selectivity and productivity is maximized by controlling the amount of coke on the catalyst while maintaining xylene yield at an acceptable value. The control of coke may be achieved by one or a combination of the following techniques: increasing catalyst on-oil time, decreasing catalyst residence time in the regenerator, reducing the air or oxygen supply to the regenerator, and decreasing catalyst circulation rate, or a combination thereof.
摘要翻译：本发明人惊奇地发现，当催化剂上的焦炭量增加时，发现对二甲苯选择性增加。在实施方案中，通过控制催化剂上的焦炭的量，同时将二甲苯收率保持在可接受的值来最大化对二甲苯选择性和生产率。焦炭的控制可以通过以下技术的一种或组合来实现：增加催化剂油中时间，减少再生器中的催化剂停留时间，减少再生器中的空气或氧气供应，以及降低催化剂循环速率，或的组合。

摘要： In a process for the production of para-xylene, methanol is preheated to a first temperature, an aromatic feedstock comprising toluene and/or benzene is preheated to a second temperature and the preheated methanol and aromatic feedstocks are fed to a reactor at a first methanol to aromatic feedstock molar ratio. The preheated aromatic feedstock is contacted with the preheated methanol under alkylation conditions in the reactor in the presence of a catalyst so that the methanol reacts with the aromatic feedstock to produce an effluent comprising para-xylene. During the reaction, a temperature is measured within the reactor and is compared with a predetermined optimal temperature. The methanol to aromatic feedstock molar ratio is then adjusted in a manner to reduce any difference between the measured and predetermined optimal temperatures in the reactor.

摘要： In a process for producing para -xylene, at least one feed comprising C 6+ aromatic hydrocarbons is supplied to a dividing wall distillation column to separate the feed into a C 7- aromatic hydrocarbon-containing stream, a C 8 aromatic hydrocarbon-containing stream and a C 9+ aromatic hydrocarbon-containing stream. At least part of the C 8 aromatic hydrocarbon- containing stream is then supplied to a para -xylene recovery unit to recover para -xylene from the C 8 aromatic hydrocarbon-containing stream and produce a para -xylene depleted stream. The para -xylene depleted stream is contacted with a xylene isomerization catalyst in a xylene isomerization zone under conditions effective to isomerize xylenes in the para - xylene depleted stream and produce an isomerized stream, which is then at least partially recycled to the para-xylene recovery unit.

摘要： In a hydrocarbon upgrading process, a hydrocarbon feed is treated in at least one of a steam cracker, catalytic cracker, coker, hydrocracker, and reformer under suitable conditions to produce a first stream comprising olefinic and aromatic hydrocarbons. A second stream composed mainly of C 4 + olefinic and aromatic hydrocarbons is recovered from the first stream and is fed together with a methylating agent to a reaction zone containing a catalyst under reaction conditions including a temperature of about 450°C to about 700°C, such that aromatics components in the second stream undergo dealkylation, trans alkylation and/or methylation and aliphatic components undergo cracking and aromatization to produce a third stream having an increased xylene content compared with said second stream and a C 3 - olefin by-product. The C 3 - olefin by-product is recovered and para- xylene is removed from at least part of said third stream.

摘要： Methylation catalysts that include surface modified zeolites may be useful for converting benzene and/or toluene via methylation with methanol and/or dimethyl ether to produce xylene products with higher than equilibrium a-xylene selectivity. For example, a methylation process may include: contacting an aromatic hydrocarbon feed with a methylating agent feed in the presence of a methylation catalyst in a methylation reactor under methylation reaction conditions to produce a methylation product mixture effluent exiting the methylation reactor, wherein the methylation catalyst comprises a modified zeolite comprising (a) a zeolite of MWW framework type, such as MCM-49, and (b) a surface modification agent on at least a portion of an outer surface of the zeolite, and the methylation product mixture effluent having a higher than equilibrium o-xylene selectivity.
