CATALYST COMPOSITION WITH HIGH EFFICIENCY FOR THE PRODUCTION OF LIGHT OLEFINS |
摘要 |
The present invention is directed to a catalyst composition for FCC which has high efficiency in the production of light olefins while maintaining the bottoms conversion. Said catalyst composition is prepared by: a) ex situ activating an olefin-selective zeolite with at least 10 wt% of a phosphorus-containing compound, calculated as P2O5 based on the total amount of olefin-selective zeolite; b) combining the activated olefin-selective zeolite with 10-40 wt% catalytic cracking component, binder, and 0-25 wt% silica in a slurry, so that the total amount of amorphous alumina present in the final catalyst composition is at least 10 wt%, and c) spray-drying the slurry to form catalyst particles. |
