The influence of gas composition on hydrogen sulfide removal from coal gas by zinc oxide sorbent was investigated at moderate temperature using TG technique. It was found that the removal of H2S by ZnO can vary greatly depending on the gas composition. Addition of H2, H2O to the inlet gas stream could promote the reaction rate, whereas the desulfurization was inhabited by CO with the concentration more than 10 %, and carbon deposit was found to be responsible for the negative effect. Dry CO2 almost had no influence on reaction, however when it was present with vapor, the competitive adsorption between two acid gases, CO2 and H2S, resulted in a decrease of reaction rate.
