Abstract: Advanced applications of producer gas (e.g. fuel cells, catalytic processes for liquid fuels production) require deep gas cleaning. Dry desulfurization technologies of fuel gas select appropriate sorbents according to material’s physical and chemical properties like sulfur capacity, attainable sulphur concentration in gas, price, etc.. The properties of a commercial sorbent were determined by means of XRD, ICP-OES, SEM and surface area measurement. The main components of the sorbent were ZnO, CuO and alumina. The content of effective metal oxides for desulfurization reaches approx. 70% , the surface area is 90.8 m2/g. The sorbent has been used as a moderate-temperature desulfurization agent (300-600oC) for H2S removal from model gas in a fixed-bed reactor. Its H2S removal properties are promising for application in clean coal technology field. The theoretical amount of sulfur capacity according to effective metal oxide content in the sorbent is 20.5 g-S/100 g.
