Patent ID: 7504021

Claim:
A catalytic cracking process, comprising: contacting a hydrocarbon feedstock with a catalytically effective amount of a cracking catalyst under catalytic conversion conditions, wherein the cracking catalyst comprises at least one amorphous, porous matrix, each matrix having pores ranging in diameter from about 1 Å to about 10 Å and pores ranging in diameter from about 40 Å to about 500 Å, but substantially free of pores ranging in size from about 10 Å to about 40 Å, wherein in the pore range from 50 Å to 250 Å, there is a single maximum in differential pore volume distribution over the 50 Å to 250 Å range; and at least one molecular sieve; wherein the amorphous, porous matrix is comprised of at least one clay, gibbsite, and at least one binder colloid.
