摘要:
이중기능촉매계를사용하여메탄올에의한톨루엔및/또는벤젠메틸화를통해파라-크실렌을제조하는유동상방법. 제1 촉매는톨루엔및/또는벤젠메틸화를달성하고, 제2 촉매는메틸화반응의부산물또는미전환메틸화제를전환시키거나, 원하는생성물의수율을개선하거나, 이의조합을달성한다. 제2 촉매의포함은 C1-C5 비방향족분획을 50% 이상억제하고방향족의형성을유의적으로증가시킬수 있다.
摘要(英):
A fluidized bed method for producing para-xylene through methylation of toluene and/or benzene with methanol using a dual function catalyst system. The first catalyst achieves toluene and/or benzene methylation, and the second catalyst converts unconverted methylation agents or by-products of the methylation reaction, improves the yield of the desired product, or achieves a combination thereof. Inclusion of the second catalyst can
inhibit the C 1 -C
5 non-aromatic fraction by 50% or more and significantly increase the formation of aromatics.
