Reactivation of Spent FCC Catalyst for the Removal of Heavy Metals from Refinery based Stimulated Waste Water
ABSTRACT The reactivation of spent FCC catalyst for its application in the adsorption of heavy metals from wastewater was investigated in this research. The most effective reactivation route of spent FCC catalyst was the oxidation of the spent FCC catalyst using hydrogen peroxide at an oxidant-to-catalyst ratio of 16 ml/g, contact time of 60 minutes and a temperature of 90oC, followed by treatment with acetic acid solution at an acid-to-catalyst ratio of 20 ml/g, 75 minutes contact time and a...
