Abstract

A process for the catalytic cracking of naphtha with a cracking zeolitic catalyst in a fluid catalytic cracking unit comprising a reactor, a regenerator and a multiplicity of elongated reaction zones, wherein said reactor contains a dense phase and a dilute phase of said catalyst and said elongated reaction zones end in said reactor, whose procedure consists of: (a) passing a stream of naphtha and a zeolitic cracking catalyst through a first elongated reaction zone, under cracking conditions of the naphtha, (b) discharging the effluent from said first elongated reaction zone in a catalyst phase contained in said reactor, said effluent being constituted by the vaporized reaction mixture and the catalyst. (c) recovering from the vaporized reaction mixture contained in said reactor a hydrocarbon fraction boiling between 1000 and 450º f (38º and 232º c), (d) passing the fraction of step (c) and a zeolitic cracking catalyst through a second elongated reaction zone, under cracking conditions of the naphtha, (e) discharging the effluent from said second elongated reaction zone in a catalyst phase contained in said reactor, said effluent being constituted by a vaporized reaction mixture and catalyst and (f) recovering from the vaporized reaction mixtures from said first and second elongated reaction zones in said reactor, streams of products selected from the group consisting of hydrocarbons and lighter, hydrocarbons and lighter and a hydrocarbon fraction boiling between 100º and 450º f (38º and 232º c), and with an octane number higher than that of naphtha.
