ZEOLITE BASED CATALYST OF ULTRA-HIGH KINETIC CONVERSION ACTIVITY

摘要

A catalyst useful in cracking of hydrocarbon feedstock comprising particulat e material composed of at least 70 weight percent zeolite and the remainder substantially composed of silica sol, alumina sol or mixtures thereof; where in the particulate material has a kinetic conversion activity of at least about 3; and compositions for fluid catalytic cracking of petroleum feedstock comprising said catalyst and a second particulate material having a kinetic conversion activity of less than 3 wherein said catalyst composition having a kinetic conversion activity of at least about 2.
