Document Type and Number:
WIPO Patent Application WO/2023/082271
Kind Code:
A1
Abstract:
Disclosed in the present application is a method for producing aromatic hydrocarbon by coupling alkane and carbon dioxide. A mixture containing alkane and carbon dioxide is in contact with a solid acid catalyst in a reactor to react to obtain an aromatic hydrocarbon compound. The alkane is selected from at least one of C2-C6 alkanes. The solid acid catalyst comprises a zeolite molecular sieve and/or a modified zeolite molecular sieve. The modified zeolite molecular sieve is a silane-modified zeolite molecular sieve. The carbon dioxide is widely derived from factory fumes, light alkane is widely derived from byproducts of petrochemical plants, the effect of turning waste into wealth is achieved, and meanwhile the pressure of carbon dioxide emission is relieved. The H/C ratio of the C2-C6 alkane products is regulated and controlled by adjusting the partial pressure of carbon dioxide, such that the purpose of high-selectivity generation of the aromatic hydrocarbon is achieved, and the high BTX selectivity and PX selectivity are obtained by modifying the outer surface of the molecular sieve with silane.
