摘要

Rare earth content is 4% to 11% by weight based on oxide, phosphorus content is 0.05% to 10% by weight based on P2O5, sodium content is 0.5% by weight or less based on sodium oxide, gallium content. Is 0.1% by weight to 2.5% by weight based on gallium oxide, the zirconium content is 0.1% by weight to 2.5% by weight based on zirconium oxide, and the total pore volume is 0.36 mL / g to 0. .48 mL / g, the ratio of the volume of secondary pores with a pore diameter of 2 nm to 100 nm to the total pore volume is about 20% to 40%, the lattice constant is 2.440 nm to 2.455 nm, and the lattice decay temperature is 1060 ° C or higher. A modified Y-type molecular sieve in which the ratio of non-skeleton aluminum content to the total aluminum content is 10% or less and the ratio of B acid to L acid in the strong acid content is 3.5 or more, a catalytic decomposition catalyst, and their production. Disclose use. When the modified Y-type molecular sieve and the catalytic cracking catalyst are used in the production of hydrogenated LCO, high LCO conversion efficiency and low coke selectivity are exhibited, and the yield of gasoline rich in BTX-based aromatic hydrocarbons is higher. High, the propylene concentration in the liquefied gas is high.
