Abstract
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.
Claims21
A molecular sieve composition comprising aluminophosphate molecular sieve particles and CO adsorbing particles, wherein:
- each CO adsorbing particle comprises at least one metal oxide selected from the group consisting of an oxide of Group IIB metal of the periodic table, an oxide of Group VIB metal of the periodic table, gallium oxide, and indium oxide,
- 90% of the aluminophosphate molecular sieve particles have diameters ranging from 0.3 mm to 9 mm, and
- 90% of the CO adsorbing particles have diameters ranging from 0.3 mm to 9 mm, and
- the molecular sieve composition does not comprise an SAPO molecular sieve.
