摘要: 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.

摘要: A process for producing ethylene includes the steps of: (1) catalytically cracking a raw material hydrocarbon to obtain a first stream containing propylene; (2) separating the first stream to obtain a C3 component stream; and (3) disproportionating the C3 component stream to obtain an ethylene stream. This process reduces the overall energy consumption of the production process and increases the total yield of the ethylene while obtaining a polymerization-grade ethylene.
