Abstract
A hydrocarbon feedstock is catalytically cracked at an elevated temperature in a cracking zone with a zeolite cracking catalyst. The cracking catalyst employed comprises a crystalline aluminosilicate zeolite catalyst and a hybrid [Al,B]-zeolite catalyst. In this process the hydrocarbon feedstock is contacted with the zeolite catalyst in, for example, a fluidized bed catalytic cracking unit to yield cracked products containing increased amounts of C.sub.3 /C.sub.8 olefins.
