Title:
メタノール及び／又はジメチルエーテルとＣ４液化ガスの混合転換によりパラキシレンを製造するための触媒及びその製造方法と使用
Document Type and Number:
Japanese Patent JP5873570
Kind Code:
B2
Abstract:
This application provides a catalyst for producing paraxylene by co-conversion of methanol and/or dimethyl ether and C 4 liquefied gas, and preparation and application thereof. The catalyst is an aromatization molecular sieve catalyst with a shape-selective function co-modified by bimetal and siloxane compound. Methanol and/or dimethyl ether and C 4 liquefied gas are fed in reactor together, wherein aromatization reaction occurring on a modified shape-selective molecular sieve catalyst. The yield of aromatics is effectively improved, in which paraxylene is the main product. In products obtained by co-conversion of methanol and/or dimethyl ether and C 4 liquefied gas, the yield of aromatics is greater than 70wt%, and the content of paraxylene in aromatics is greater than 80wt%, and the selectivity of paraxylene in xylene is greater than 99wt%.
