The present invention relates to a modified metal zeolite type Y for use as a catalyst for catalytic cracking, which contains 1-15 weight. % of metal IVB group in terms of oxide, while the ratio of deformed tetrahedrally coordinated frame aluminum to tetrahedrally coordinated frame aluminum in the structure of the zeolite lattice is 0.1-0.8. The invention relates to two variants of the method of its production and the catalyst based on this zeolite. 5 n. and 47 hp f-ly, 2 ill., 45 Ave., 14 tab. |
