Abstract
A catalyst composition suitable for reacting hydrocarbons such as in fluidized catalytic cracking (FCC) comprises an attrition-resistant particulate having at least 30% of an intermediate pore zeolite, kaolin, a phosphorous compound, and a high density unreactive component. An example of an unreactive component is alpha-alumina. The catalyst can also contain a reactive alumina of high surface area.
Claims7
A process for chemically and catalytically reacting a hydrocarbon feed comprising contacting the feed at catalytic reactive conditions with a catalyst comprising (a) at least about 30% by weight of an intermediate pore zeolite, (b) about 3-15% by weight phosphorus, measured as P2O5, (c) about 15 to 45% by weight kaolin, and (d) an unreactive metal-containing component other than kaolin with a BET surface area of less than 50 m2/g.
