Abstract: Particulate catalytic cracking catalysts which comprise a zeolite having catalytic cracking ability under catalytic cracking conditions, added silica, a magnesium salt, an alumina containing binder, clay and optionally, 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 coke and hydrogen selectivity without the need to incorporate rare earth metals.

Abstract: 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.

Abstract: A process for catalytic cracking of an iron-contaminated fluid catalytic cracking (FCC) feedstock. The process may include combining a FCC catalyst, a slurry containing a magnesium compound, and an iron-contaminated FCC feedstock during a FCC process under fluid catalytic cracking conditions, thereby generating an equilibrium FCC catalyst with reduced iron poisoning. The slurry containing the magnesium compound may not contain a calcium compound.

Abstract: 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.
