HYDROCARBON CONVERSION CATALYST Russian patent published in 2011 - IPC B01J29/80 B01J29/72 B01J29/76 B01J29/40 C10G11/05 

FIELD: chemistry.

SUBSTANCE: invention relates to hydrocarbon conversion catalysts containing zeolite. Described is hydrocarbon conversion catalyst containing the following (of total weight of catalyst): 1-60 wt % mixture of zeolites, 5-99 wt % heat-resistant inorganic oxide and 0-70 wt % clay, where the mixture of zeolites contains the following (of the total weight of the mixture): 1-75 wt % beta-zeolite, modified with phosphorus and a transition metal M, 25-99 wt % zeolite with MFI-structure and 0-74 wt % zeolite with large pores, where the anhydrous chemical composition of the beta-zeolite modified with phosphorus and transition metal M has the following formula: (0-0.3)Na₂O·(0.5-10)Al₂O₃·(1.3-10)P₂O₅·(0.7-15)M_xO_y·(64-97) SiO₂ (weight percentages of oxides are indicated in the brackets), where the transition metal M is one or more metals selected from a group comprising Fe, Co, Ni, Cu, Mn, Zn and Sn; x is the number of atoms of the transition metal M, and y is the number for which valence, which corresponds to oxidation state of transition metal M, is provided.

EFFECT: high conversion capacity of petroleum hydrocarbons and higher output of light olefins, especially propylene.
