Comparative study of the reactions of metal oxides with H{sub 2}S and SO{sub 2}
Primary objective was to investigate the effects of pore structure on capacity of porous metal oxides for removal of SO{sub 2} from power plant fuel gas and H{sub 2}S from hot coal gas. During this period, a comparative study was carried out on the direct reaction with H{sub 2}S and SO{sub 2} of the...
