A method of using spent silica-alumina catalyst previously used in a fluid-bed type catalytic cracking process by contacting a volume of particles of the spent catalyst with a liquid and allowing the spent catalyst particles to absorb at least a portion of the liquid. The method is particularly useful in the removal of hazardous liquid spills.
