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 du

대표청구항 ▼

1. 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. 2. The metal trap particle of claim 1, wherein said spray dried mixture is calcined at 1500° F. 3. The metal trap particle of claim 1, wherein said spray dried mixture comprises 20-90% wt. % kaolin, 5-50 wt. % magnesium oxide or magnesium hydroxide and 5-50 wt. % calcium carbonate. 4. The metal trap particle of claim 3, wherein said spray dried mixture comprises 40-80 wt. % kaolin, 10-40 wt. % magnesium oxide or magnesium hydroxide and 10-40 wt. % calcium carbonate. 5. The metal trap particle of claim 1, wherein said spray dried mixture contains magnesium hydroxide. 6. The metal trap particle of claim 1, wherein the calcined spray dried mixture contains at least about 10% magnesium oxide. 7. The metal trap particle of claim 6, wherein the calcined spray dried mixture contains 15-30 wt. % magnesium oxide. 8. The metal trap particle of claim 1, wherein the calcined spray dried mixture contains greater than 50% of the magnesium in the form of Periclase MgO. 9. The metal trap particle of claim 1, wherein the calcined spray dried mixture has an average particle size of 50-150 microns. 10. The metal trap particle of claim 1, wherein kaolin comprises a mixture of hydrous kaolin and calcined kaolin. 11. 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. 12. The method of claim 11, wherein said spray dried particle is calcined at 1500° F. 13. The method of claim 11, wherein said spray dried mixture comprises 30-90% wt. % kaolin, 5-50 wt. % magnesium oxide or magnesium hydroxide and 5-50 wt. % calcium carbonate. 14. The method of claim 13, wherein said spray dried mixture comprises 40-80 wt. % kaolin, 10-40 wt. % magnesium oxide or magnesium hydroxide and 10-40 wt. % calcium carbonate. 15. The method of claim 11, wherein said spray dried mixture contains magnesium hydroxide. 16. The method of claim 11, wherein said calcined spray dried mixture contains 15-30 wt. % magnesium oxide. 17. The method of claim 11, wherein said calcined spray dried mixture has an average particle size of 50-150 microns. 18. The method of claim 11, wherein the calcined spray dried mixture contains greater than 50 percent of the magnesium in the form of Periclase MgO. 19. The method of claim 11, wherein kaolin comprises a mixture of hydrous kaolin and calcined kaolin. 20. The method of claim 11, wherein said metal trap comprises 2 to 50% by weight of said mixture of said cracking catalyst and said trap.
