Catalytic composition and catalytic cracking method in a fluidised bed using such a composition

摘要

Catalytic composition (A) for fluidized bed catalytic cracking (FCC), comprises an amorphous catalytic component (I) (50-99.5 wt.%) containing at least an amorphous mesoporous and/or macroporous metallic oxide such as silica, alumina or aluminosilicates and a crystalline catalytic component (II) (0.5-50 wt.%) containing a microporous crystalline aluminosilicate, where the composition is free from zeolite Y. Independent claims are included for: (1) a process of moving or circulating fluidized bed catalytic cracking of a hydrocarbon charge having boiling temperature >=350[deg]C, using the composition (A) as cracking catalyst in a reaction zone of cracking; and (2) hydrocarbon product obtained by the process.
