Method of operation of a dry type simultaneous desulfurization and dedusting apparatus

摘要

A dry type simultaneous desulfurization and dedusting method directed to forming moving beds with granulate desulfurizing and dedusting agent containing as the principle composition 5-95 weight % of iron oxide and 95-5 weight % of metallic iron, and contacting these moving beds with the gas containing hydrogen sulfide and dust, thereby simultaneously desulfurizing and dedusting the gas.
