Title:
METHOD FOR PREPARING AROMATIC HYDROCARBONS FROM METHANOL AND/OR DIMETHYL ETHER
Document Type and Number:
WIPO Patent Application WO/2024/036466
Kind Code:
A1
Abstract:
The present invention provides a method for preparing aromatic hydrocarbons from methanol and/or dimethyl ether. The method comprises: making a material containing methanol and/or dimethyl ether contact a catalyst for reaction to obtain aromatic hydrocarbons, wherein the catalyst is a metal-modified molecular sieve catalyst, and the pressure of the reaction is 7-15 MPa. Compared with the prior art, the reaction of methanol and dimethyl ether to aromatic hydrocarbons under high-pressure atmosphere in the method provided by the present application can improve and stabilize the selectivity of aromatic hydrocarbons, especially BTX, and prolong the single-pass life of the catalyst.
