Abstract

Improvements made to a process for catalytic cracking of a multiplicity of virgin gas-oils with a zeolitic cracking catalyst in a fluid catalytic cracking unit, comprising a reactor, a regenerator and a multiplicity of elongated reaction zones, in which said reactor contains a dense phase and a diluted phase of said catalyst and the mentioned elongated reaction zones end in said reactor and in which the mixtures of said gas-oils and catalyst are passed through said elongated reaction zones in catalytic cracking conditions to said reactor, characterized by said improvements consisting of: (a) passing through at least one elongated reaction zone a virgin gas oil with a boiling range of between 500º and 1050ºF (260 and 550ºC), (b) passing through at least one other elongated reaction zone a virgin gas oil with a boiling range of between 450º and 750ºF (221º and 399ºC), said gas oil from step (a) having a boiling range higher than that of the diesel oil in step (b) and (c) discharging the effluent from said elongated reaction zones in a catalyst phase contained in said reactor, said effluent being constituted by a vaporized reaction mixture, and the catalyst, with the conversion of gas oil to a boiling range being more high 0-30% lower in volume than lower boiling range diesel oil.
