Abstract
The present invention is directed to catalytic cracking additives comprising a metals trapping material; and a high activity catalyst. The present invention is directed to processes for the catalytic cracking of feedstock comprising contacting said feedstock under catalytic cracking conditions with a composition comprising a bulk catalyst and a catalytic cracking additive, wherein the catalytic cracking additive comprises a metals trapping material; and a high activity catalyst. The invention is also directed to processes for increasing the performance of a bulk catalyst in the presence of at least one metal comprising contacting a feedstock with a catalytic cracking additive comprising a metals trapping material; and a high activity catalyst.
Claims18
A process for the catalytic cracking of feedstock comprising contacting said feedstock under catalytic cracking conditions with a composition comprising a bulk catalyst, wherein the bulk catalyst has a surface area of less than about 300 m2/g, and a catalytic cracking additive, wherein the catalytic cracking additive comprises:
- a) a metals trapping material;
- and
- b) a high activity catalyst, wherein the high activity catalyst has a surface area of greater than about 350 m2/g.
