PROCESS FOR PRODUCING PARAXYLENE BY METHYLATION OF BENZENE AND/OR TOLUENE
알킬화 반응 구역에서 알킬화 조건하에 알킬화 촉매의 존재하에 벤젠 및/또는 톨루엔을 포함하는 방향족 탄화수소 공급원료를 메탄올 및/또는 디메틸 에테르를 포함하는 알킬화 시약과 접촉시켜 크실렌을 포함하는 알킬화된 방향족 생성물을 생성하는, 파라크실렌의 제조 방법이 기재된다. 알킬화 촉매는 구속 지수 ≤ 5를 갖는 분자체를 포함하며, 알킬화 조건은 500℃ 미만의 온도를 포함한다. 파라크실렌은 이후에 알킬화된 방향족 생성물로부터 회수될 수 있다. A process is described for producing paraxylene, i...

A process is described for producing paraxylene, in which an aromatic hydrocarbon feedstock comprising benzene and/or toluene is contacted with an alkylating reagent comprising methanol and/or dimethyl ether in an alkylation reaction zone under alkylation conditions in the presence of an alkylation catalyst to produce an alkylated aromatic product comprising xylenes. The alkylation catalyst comprises a molecular sieve having a Constraint Index≤5, and the alkylation conditions comprise a temperature less than 500° C. Paraxylene may then be recovered from the alkylated aromatic product. |
