ABSTRACT:
An improvement in iso-olefin production without substantial decrease in overall yield is obtained in an integrated process combining a fluidized catalytic cracking reaction and a fluidized catalyst olefin interconversion reaction when crystalline medium pore shape selective zeolite catalyst particles are withdrawn in partially deactivated form from the interconversion reaction stage and added as part of the active catalyst in the FCC reaction.
