FIELD: technological processes.
SUBSTANCE: microspherical catalyst for cracking petroleum fractions has been proposed, which includes ultrastable zeolite Y in cation-decationated form and a matrix, the components of which use amorphous aluminosilicate, aluminum oxide and natural clay. As a component, the matrix contains kaolin clay modified with sodium polyphosphate in the following ratio of components in the catalyst, wt. %: zeolite Y 18–25; amorphous aluminosilicate 20–40; aluminum oxide 10–40; kaolin clay 10–30.
EFFECT: obtaining a durable highly active cracking catalyst, providing an increased yield of gasoline.
