Highly active adsorbent for hot gas desulfurization was developed by preparing zinc ferrite and calcium ferrite in the presence of Yallown coal. Coal-supported ferrites exhibited larger desulfurization capacity than unsupported ferrites. Coal-supported ferrites could efficiently remove 4000ppm of H_2S to less than a few ppm. Coal-supported zinc ferrite could be regenerated by air oxidation at 450℃, the regenerated ferrite showed the same H_2S absorption capability as that of fresh one.
