CATALYST FOR FLUIDIZED-BED CATALYTIC CRACKING OF HEAVY HYDROCARBONS AND FLUIDIZED-BED CATALYTIC CRACKING PROCESS

摘要

FIELD: petroleum processing.;SUBSTANCE: catalyst represents a mixture comprising: particulate catalyst prepared by homogenously dispersing crystalline aluminosilicate zeolite in inorganic oxide matrix and particulate additive-type catalyst deactivating metals impairing catalyst and contained in oil feedstock, un which catalyst calcium carbonate with average particle diameter 0.001 to 30 m is dispersed in inorganic matrix through which amount of said calcium carbonate achieved 30 to 70% based on dry material. Ratio of catalyst to additive-type catalyst ranges between 99.9:1 and 50:50. Catalyst shows excellent cracking power and is able to process petroleum distillation residues.;EFFECT: increased catalytic activity and prolonged lifetime.;3 cl, 8 dwg, 11 tbl, 14 ex
