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.
