GRANULAR CRACKING CATALYST MANUFACTURING METHOD Russian patent published in 2014 - IPC B01J37/04 B01J37/08 B01J2/00 C10G11/05 B01J35/02 B01J29/08 B01J21/16 B82B1/00 

FIELD: oil and gas industry.

SUBSTANCE: invention is related to oil processing, in particular to manufacturing method of cracking catalyst for heavy and bottom fractions. The claimed method for manufacturing of granulated cracking catalyst includes introduction of Y-type zeolite to the carrier containing colloidal components and/or their precursors, formation and thermal treatment. At that colloidal components and/or their precursors are interaction products of nanoscale compounds of tetrahedron type of [SiO₄]^- and [AlO₄]⁺ composed of natural and/or synthetic aluminosilicates with acids or salts, mixtures are made by extrusion at sol-gel stage and thermal treatment is preceded by hold-up time without heating.

EFFECT: suggested method allows production of granular catalysts with high mechanical properties and high activity as well improvement of the technology and increase in productivity.
