Disclosed is a process for making middle distillate and lower olefins. The process includes catalytically cracking a gas oil feedstock within a riser reactor zone by contacting under suitable catalytic cracking conditions within the riser reactor zone the gas oil feedstock with a middle distillate selective cracking catalyst that comprises amorphous silica alumina and a zeolite to yield a cracked gas oil product and a spent cracking catalyst. The spent cracking catalyst is regenerated to yield a regenerated cracking catalyst. Within an intermediate cracking reactor such as a dense bed reactor zone and under suitable high severity cracking conditions a gasoline feedstock is contacted with the regenerated cracking catalyst to yield a cracked gasoline product and a used regenerated cracking catalyst. The used regenerated cracking catalyst is utilized as the middle distillate selective catalyst.

Method and apparatus for making a middle distillate product and lower olefins from a hydrocarbon feedstock

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.

Hydrocarbon cracking process for converting gas oil preferentially to middle distillate and lower olefins

Process for radial distribution of fluid into a fluid mass wherein fluid is radially conveyed within and isolated from the fluid mass and discharged via a plurality of distribution points located radially in the fluid mass.
