Attrition resistant catalysts and sorbents based on heavy metal poisoned FCC catalysts

A heavy metal poisoned, spent FCC catalyst is treated bychemically impregnating the poisoned catalyst with a new catalyticmetal or metal salt to provide an attrition resistant catalyst orsorbent for a different catalytic or absorption processes, such ascatalysts for Fischer-Tropsh Synthesis, and sorbents for removal ofsulfur gasses from fuel gases and flue-gases. The heavy metalcontaminated FCC catalyst is directly used as a support forpreparing catalysts having new catalytic properties and sorbentshaving new sorbent properties, without removing or "passivating"the heavy metals on the spent FCC catalyst as an intermediatestep.
