A catalyst contains a metal oxide, and a molecular sieve, in a crystal form, having a topological pore structure. The metal oxide is centrally distributed on the surface of the molecular sieve. Grains of the molecular sieve are exposed to at least three families of crystal planes. The family of crystal plane with the largest pore size in topology is occupied by the metal oxide by no more than 30%, preferably no more than 20%, or no more than 10%.

Catalyst including molecular sieve having topological pore structure, preparation method therefor and use thereof

The invention relates to a molecular sieve composition, a process of preparing same and use thereof in the production of lower olefins. The molecular sieve composition comprises an aluminophosphate molecular sieve and a CO adsorbing component, both of which are present independently of each other. When the molecular sieve composition is used as a catalyst for producing lower olefins using synthesis gas as a raw material, the molecular sieve composition has the advantages of high selectivity to lower olefins and the like.
