PROCEDURE FOR CATALYTIC CONVERSION OF HYDROCARBONS Russian patent published in 2011 - IPC C10G11/05 B01J29/80 B01J29/72 B01J29/76 

FIELD: oil and gas production.

SUBSTANCE: invention refers to procedure for catalytic conversion of hydrocarbons. The procedure consists in contacting source hydrocarbons with catalyst of hydrocarbon conversion to ensure reaction of catalytic cracking in a reactor. Further, products of reaction are withdrawn from the reactor and are divided into fractions to produce light olefines, gasoline, diesel fuel, heavy diesel fuel and other saturated low-molecule hydrocarbons. Also, catalyst of hydrocarbons conversion contains (of total weight of catalyst): 1-60 % wt of mixture of zeolite, 5-99 % wt of heat-resistant non-organic oxide and 0-70 % wt of clay. Mixture of zeolite contains (from total weight of mixture): 1-75 % wt of beta-zeolite modified with phosphorus and transition metal M, 25-99 % wt of zeolite with MF-structure and 0-74 % wt of zeolite of large pores. Waterless chemical composition of beta-zeolite modified with phosphorus and transition metal M is of the following kind: (0-0.3)Na₂O·(0.5-10)Al₂O₃·(1.3-10)P₂O₅·(0.7-15)M_xO_y·(64-97)SiO₂ (in brackets there are indicated wt percents of oxides) where transition metal M is one or several metals chosen from a group consisting of Fe, Co, Ni, Cu, Mn, Zn and Sn; x is number of atoms of transition metal M, and y is number ensuring valence corresponding to a degree of transition metal M oxidation.

EFFECT: increased conversion of hydrocarbons of oil and higher output of light olefines, particularly, propylene.
