摘要

"Catalu00ectico fluidized cracking catalyst, manufacturing method of a fluidized catalyst cracking catalu00ectico; and method for cracking a hydrocarbon supply.This is a catalyst for fluidized catalytic cracking, made from kaolin microspheres containing initially.An alumina boemita capable of dispersion and a sodium silicate or silica sol binder.The part of kaolin containing hydrous kaolin and, optionally, spinel and mullite, or both the spinel and mullite.Made by kaolin was calcined through its exoterma characteristic.The calcination of hydrated clay to metacaulim and training zeolu00edtica insitu, by treatment with sodium silicate.Yields a catalyst containing Y - faujasita and transforms the boemita capable of dispersion in transitional alumina.The catalyst can be used for crack waste or supplies containing residues.To the extent that the phase of alumina formed from the boemita capable of dispersion apassiva contaminants of nickel and vanadium.
