Abstract
A catalytic additive comprising an intermediate pore zeolite, such as ZSM-5 is treated so as to improve propylene yields when the additive is included in a FCC catalytic inventory by first treating the zeolite with a phosphorus compound to incorporate the phosphorus in the zeolite, and mixing the P-treated zeolite with a matrix component comprising kaolin and another phosphorus-containing compound.
