Abstract EN

Large quantity of catalysts are used in a general fertilizer company in Homs which contain Aluminium and Zinc.

This paper presents a study of the recovery of Aluminium, Zinc from spent catalysts to avoid the pollution of the environment and reuse the Aluminium, Zinc in industrial ranges.

The leaching of catalyst was studied in many acids and sulfuric acid found to be most effective.

The optimal condition of spent catalysts leaching has been studied with various concentrations of sulfuric acid at different temperatures and mixing times.

Zinc was precipitated as ZnSO4 by adding ethyl alcohol to the aqueous solution
