PREPARATION OF DESULPHURISATION MATERIALS

摘要

A process for the preparation of a desulfurization material includes: (i) forming a zinc/aluminium hydrotalcite composition, and (ii) calcining the composition to form a zinc oxide/alumina material, in which one or more nickel compounds are included in the hydrotalcite formation step, and/or are impregnated onto the hydrotalcite composition and/or the calcined zinc oxide/alumina material, and the resulting composition dried and recovered.
