The invention discloses a renewable compound metal oxide high-temperature coal gas desulfurizer which is an ferric oxide-cerium oxide-zirconium oxide based compound metal oxide high-temperature coal gas desulfurizer which is formed by using ferric nitrate, cerous nitrate and zirconyl nitrate as the main raw materials and adding an adhesive and a pore forming material through extrusion-molding. The main desulfurization activated components of the desulfurizer are activated ferric oxide and activated cerium oxide, the desulfurization catalyst is activated zirconium oxide, the contents of the three desulfurizer components include 30-40 wt% of Fe2O3, 50-60 wt% of CeO2 and 5-15 wt% of ZrO2, and the high-temperature coal gas desulfurizer is high in desulfurization sulfur capacity, desulfurization precision and activated component utilization rate and low in desulfurization and regeneration temperature.
