Summary: | An improved process and catalyst composition for cracking hydrocarbons in a fluidized cracking process are disclosed. The process employs circulating inventory of a regenerated cracking having a minimal carbon content. The regenerated catalyst comprises a catalyst/additive composition which contains a pentasil zeolite, iron oxide, and a phosphorous compound. In accordance with the present disclosure, the catalyst/additive contains controlled amounts of iron oxide which is maintained in an oxidized state by maintaining low amounts of carbon on the regenerated catalyst inventory. In this manner it was discovered that the catalyst composition greatly enhances the production and selectivity of light hydrocarbons, such as propylene. |
