Abstract
The present invention provides a catalyst composition comprising rare earth exchanged USY zeolite (REUSY); pentasil zeolite; phosphorous compound; clay, silica, alumina, and spinel to enhance the catalytic activity and selectivity for light olefins in FCC operation conditions. The present invention also provides a process for the preparation of Light olefin enhancing catalyst composition with high propylene yield and coke selectivity.
Claims10
A composite catalyst composition, the composition comprising:
- about 10-25 wt % rare earth exchanged USY zeolite (REUSY);
- about 5-20 wt % pentasil zeolite;
- about 2-8 wt % phosphorous compound;
- about 20-45 wt % clay;
- about 5-25 wt % silica;
- about 10-35 wt % alumina;
- and
- about 0.5 to 3 wt % mixed metal oxide selected from a group consisting of at least one metal of Group 11 and one metal of Group 13, and the wt % being based on total weight of the catalyst composition.
