This paper summarizes the research progress of the removal of hydrogen sulfide from coal gas by the dry method with activated-carbon

metal oxides

complex metal oxides and activated-carbon supported metal oxides.The characteristics of activated-carbon and metal oxides as sorbents are analyzed

including treatment temperature

desulfurization efficiency and regeneration

etc.The complex metal oxides and activated-carbon supported metal oxides are regarded as prospective sorbents for industrial applications and have better performance during desulfurization and regeneration.According to the mechanisms of desulfurization

it is feasible to prepare sorbents for desulfurization with semi-coke and metal oxides due to the similarity of semi-coke and activated carbon in their properties.
