Title:
A CATALYST FOR CONVERTING HYDROCARBONS
Document Type and Number:
WIPO Patent Application WO/2008/034299
Kind Code:
A1
Abstract:
A catalyst for converting hydrocarbons comprises l-60wt% zeolite mixture, 5-99wt% refractory inorganic oxide and 0-70wt% clay, based on the total weight of the catalyst. It is characterized in that the zeolite mixture includes l-75wt% beta zeolite modified by phosphorus and transition metal M, 25-99wt% zeolite with MFI structure and 0-74wt% large pore size zeolite based on the total weight of the zeolite mixture. The anhydrous composition of the beta zeolite modified by phosphorus and transition metal M expressed as a weight percentage based on oxide is given by: (0-0.3) Na2O-(O-S-IO) Al2O3 (1.3-10) P2O5-(0.7-15) MxO/(64-97) SiO2, wherein M is selected from the group consisting of Fe, Co, Ni, Cu, Mh, Zn and Sn, x represents the molecular number of M, y represents the number needed for the oxidation state of M. The catalyst of this invention has enhanced conversion ability of hydrocarbons, and increased yield of low carbon olefins, especially increased yield of propylene. The catalyst of this invention can be used in catalytic cracking process of hydrocarbons to produce low carbon olefins.
