Abstract:
1. A catalyst for fluidized catalytic cracking comprising alumina, phosphorous and molecular sieve, wherein said alumina comprises η-alumina, χ-alumina, and γ-alumina, and wherein the catalyst comprises, on the basis of the total amount of the catalyst: 0.5-50 wt % of η-alumina; less than 50 wt % of χ-alumina and γ-alumina; 10-70 wt % of molecular sieve, said molecular sieve is one or more selected from the group consisting of large pore zeolites and medium pore zeolites; greater than 0 to 75 wt % of clay; 0.1-5.5 wt % of phosphorous, measured as P 0.1-2 wt % of rare earth metal, measured as oxide, wherein the phosphorous is impregnated in the catalyst.
