Abstract
A rare earth-containing Y zeolite has at least two mesopore pore-size distributions at 2-3 nanometers and 3-4 nanometers. A catalytic cracking catalyst contains the rare earth-containing Y zeolite. When used in the catalytic cracking of heavy oil, the catalytic cracking catalyst invention has excellent heavy oil conversion ability, higher gasoline yield, and lower coke selectivity.
