Abstract: The sulfur content of liquid cracking products, especially the cracked gasoline, of the catalytic cracking process is reduced by the use of a sulfur reduction catalyst composition comprising a porous molecular sieve which contains a metal in an oxidation state above zero within the interior of the pore structure of the sieve as well as a cerium component which enhances the stability and sulfur reduction activity of the catalyst. The molecular sieve is normally a faujasite such as USY. The primary sulfur reduction component is normally a metal of Period 3 of the Periodic Table, preferably vanadium. The sulfur reduction catalyst may be used in the form of a separate particle additive or as a component of an integrated cracking/sulfur reduction catalyst.

Abstract: The sulfur content of liquid cracking products, especially the cracked gasoline, is reduced in a catalytic cracking process employing a cracking catalyst containing a high content of vanadium. The cracking process involves introducing at least one vanadium compound into a hydrocarbon-sulfur containing feedstock to be charged to a fluid catalytic cracking reactor operating under steady state conditions and containing an equilibrium fluid cracking catalyst inventory within the reactor. The amount of sulfur in the liquid products, in particular gasoline and LCO fractions, is reduced as a result of the increased vanadium content on the equilibrium catalyst. Advantageously, sulfur reduction is achieved even in the presence of other metal contaminants, such as nickel and iron, on the equilibrium catalyst.

Abstract: A catalyst composition suitable for reacting hydrocarbons, e.g., conversion processes such as fluidized catalytic cracking (FCC) of hydrocarbons, comprises attrition resistant particulate having a high level (30-85%) of stabilized zeolites having a constraint index of 1 to 12. The stabilized zeolite is bound by a phosphorous compound, alumina and optional binders wherein the alumina added to make the catalyst is about 10% by weight or less and the molar ratio of phosphorous (P2O5) to total alumina is sufficient to obtain an attrition index of about 20 or less. The composition can be used as a catalyst per se or as additive catalyst to a conventional catalyst and is especially suitable for enhancing yields of light olefins, and particularly ethylene, produced during conversion processes.
