ABSTRACT:
A process for preparation of fluidized catalytic cracking (FCC) catalyst, comprising silicon stabilized large crystallite sized synthetic faujasite zeolite, aluminum depleted and normal kaolin clay, alumina and silica. The cracking catalyst is highly active and selective for bottom upgradation, it produces less coke and higher gasoline and total cycle oil (TCO) and possesses improved metal tolerance properties when evaluated and compared with a commercial catalyst under conditions of a typical FCC unit in a petroleum refinery.
