Avidan, A A; Chou, T S

A continuous multi-stage process is described for producing liquid hydrocarbons from crackable petroleum feedstock comprising: contacting the feedstock in a primary fluidized catalyst reaction stage with a mixed catalyst system; separating the olefinic gas and contacting the olefins with particulate catalyst solids consisting essentially of medium pore siliceous zeolite catalyst in a secondary fluidized bed reaction stage under reaction severity conditions effective to upgrade the olefins to mostly C/sub 5//sup +/ hydrocarbons, thereby depositing carbonaceous material onto the particulate zeolite catalyst to obtain an equilibrium catalyst; withdrawing a portion of partially deactivated equilibrium particulate zeolite catalyst from the secondary reaction stage and regenerating the equilibrium catalyst; and adding a portion of the regenerated zeolite catalyst to the primary fluidized reaction stage for conversion of crackable petroleum feedstock.
