A heavy metal poisoned, spent FCC catalyst is treated by chemically impregnating the poisoned catalyst with a new catalytic metal or metal salt to provide an attrition resistant catalyst or sorbent for a different catalytic or absorption processes, such as catalysts for Fischer-Tropsh Synthesis, and sorbents for removal of sulfur gasses from fuel gases and flue-gases. The heavy metal contaminated FCC catalyst is directly used as a support for preparing catalysts having new catalytic properties and sorbents having new sorbent properties, without removing or "passivating" the heavy metals on the spent FCC catalyst as an intermediate step.

[ That which is claimed is:] [1.] A process for the preparation of a fluidizable, particulate, attrition resistant, supported sorbent or catalyst comprising:impregnating a substantially spent, fluid catalytic cracking catalyst comprising fluid catalytic cracking metal poisons selected from the group consisting of nickel and vanadium, with at least one compound of a metal having catalytic or sorbent properties for a predetermined catalytic or absorption conversion process; andtreating said impregnated substantially spent, fluid catalytic cracking catalyst to convert said metal compound to an active state for said predetermined conversion process and wherein said process is free of any steps to remove or passivate said metal poisons on said substantially spent fluid catalytic cracking catalyst.
