METHOD OF PRODUCING FLUID CATALYTIC CRACKING CATALYSTS WITH REDUCED ATTRITION RATES Russian patent published in 2018 - IPC C10G11/18 B01J29/06 B01J35/10 B01J35/08 B01J35/04 B01J37/04 B01J37/08 B01J29/08 B01J29/04 

FIELD: technological processes.

SUBSTANCE: fluid catalytic cracking zeolite-containing catalyst microsphere comprising zeolite, wherein said microsphere is formed from slurry, comprising: i) kaolin, that has been calcined through its exotherm; and (ii) zeolite crystals, or iii) hydrated kaolin and/or metakaolin, the slurry is mixed with 0.005–0.5 wt. % of the cationic polyelectrolyte with respect to the mass i) + ii) or i) + iii) before or during formation of said microsphere. Method of making a catalytic microsphere is also provided.

EFFECT: provide fluid catalytic cracking catalysts having improved resistance to wear.
