ORGANIC BASE-MODIFIED COMPOSITE CATALYST AND METHOD FOR SYNTHESIS OF ETHYLENE BY HYDROGENATION OF CARBON MONOXIDE Russian patent published in 2021 - IPC B01J29/18 B01J29/26 

FIELD: chemistry.

SUBSTANCE: invention relates to a catalyst for producing ethylene using a synthesis gas reaction, wherein the catalyst contains a component I and a component II; the component I and the component II are combined by means of mechanical stirring; the active component of the component I is a metal oxide with a high specific surface area; the component II constitutes a molecular sieve with a MOR topological structure; in the component II, said molecular sieve with a MOR topological structure is modified with a fatty amine, wherein the modification constitutes dispersing the fatty amines at acid sites B in channels formed by 12-membered rings in said molecular sieve with a MOR topological structure. The invention also relates to a method for highly selective production of ethylene using a synthesis gas reaction.

EFFECT: synthesis of low-carbon olefins and achieved selectivity in relation to C₂-C₃-olefins - 78 to 87%, ethylene as a separate product - 75 to 82%, methane - less than 9%, alkanes C4 or higher - less than 10%.
