Method fo preparing fluidizable sorbent compositions useful for removal of hydrogen sulfide

摘要

Method of making a ZnO-based sorbent compsn. suitable for use in a fluidised bed, comprising: (a) impregnating a mixt. of Al2O3, SiO2 and ZnO with an aq. soln. of a promoter metal contg. cpd. to form an impregnated mixt.; (b) agglomerating the impregnated mixt. to form an agglomerate; and (c) granulating the agglomerate to produce a granulated material. Also claimed is fluidisable sorbent comprising a particulate consisting essentially of Al2O3, SiO2 and ZnO, having a mean particle size of 20-500 microns.
