摘要： A rare earth free particulate catalytic cracking catalyst which comprises a zeolite having catalytic cracking ability under catalytic cracking conditions, an acidified silica sol binder, magnesium salt, clay and a matrix material. The catalytic cracking catalyst has a high matrix surface area and is useful in a catalytic cracking process, in particularly, a fluid catalytic cracking process, to provide increased catalytic activity and improved hydrogen and coke selectivity without the need to incorporate rare earth metals.

摘要： A rare earth free, ultra low soda, particulate fluid catalytic cracking catalyst which comprises a reduced soda zeolite having fluid catalytic cracking ability under fluid catalytic cracking conditions, a magnesium salt, an inorganic binder, clay and optionally, a matrix material. The catalytic cracking catalyst is useful in a fluid catalytic cracking process to provide increased catalytic activity, and improved coke and hydrogen selectivity without the need to incorporate rare earth metals.

摘要： 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.
