Abstract
A metal trap particle used for passivation of metals during FCC cracking comprises a calcined spray dried particle formed from kaolin, magnesium oxide or magnesium hydroxide and calcium carbonate. The metal trap particle contains at least 10 wt. % magnesium oxide which improves metals passivation during FCC cracking.
Claims20
A metal trap particle used to passivate metals during FCC processing comprising a spray dried mixture of kaolin, magnesium oxide or magnesium hydroxide, and calcium carbonate, said spray dried mixture having been calcined at a temperature of from 1500° F. to less than 1650° F.
A method of metal passivation during fluid catalytic cracking (FCC) comprising:
- (a) contacting a metal-containing hydrocarbon fluid stream in an FCC unit comprising a mixture of a fluid catalytic cracking catalyst and a particulate metal trap;
- (b) said particulate metal trap comprising a spray dried mixture of kaolin, magnesium oxide or magnesium hydroxide, and calcium carbonate, said spray dried mixture being calcined at a temperature of 1500° F. to less than 1650° F. and wherein said metal trap contains at least 10 wt. % magnesium oxide.
