Abstract
Described is a hydrocarbon cracking process for converting a heavy hydrocarbon feedstock selectively to middle distillate and lower olefins by catalytically cracking a heavy hydrocarbon feedstock within a riser reactor zone by contacting the heavy hydrocarbon feedstock with both a middle distillate selective cracking catalyst in combination with a shape selective zeolite additive under suitable catalytic cracking reaction conditions.
