Title:
CATALYST FOR CARBONYLATION OF DIMETHYL ETHER TO PRODUCE METHYL ACETATE, PREPARATION METHOD THEREFOR, AND USE THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/092794
Kind Code:
A1
Abstract:
Disclosed are a catalyst for the carbonylation of dimethyl ether to produce methyl acetate, a preparation method therefor, and the use thereof. The catalyst contains a modified H-MOR molecular sieve, wherein the modified H-MOR molecular sieve is prepared by means of the exchange of an H-MOR molecular sieve with a pyridinium salt. Methyl acetate is produced by passing dimethyl ether and a raw material gas containing carbon monoxide through a reactor charged with an acidic molecular sieve catalyst which selectively regulates active sites, and performing a reaction under the conditions of a reaction temperature of 150-280°C, a reaction pressure of 0.5-25.0 MPa, and a space velocity of dimethyl ether of 0.2-4 h -1.
