Abstract

A modified alumina is useful as metals passivator in fluidizable catalytic cracking catalysts. The modified alumina is prepared from a hydrated alumina, e.g., gibbsite, which is reacted with a low-molecular weight organic acid, e.g., acetic acid, forming aluminum salts. Calcination of the modified alumina results in decomposition of the aluminum salt.
