Preparation of sorbents on hot gas desulfurization

摘要

It is well known that intgration gasification combined cycle (IGCC) and molten carbonate fuel cell (MCFC) processes are advanced power generation technologies with high efficiency power generation and environmental performance. The advantages of IGCC and MCFC system over pulverized coal fired power generation are higher power generation efficiency , lower air pollutants emission[1,2,3]. Therefore, IGCC and MCFC are expected to be main spearhead in the future for power required. Coal gasification generates large amounts of pollutants, such as particles, hydrogen sulfide and hydrogen chloride representing a serious problem. Among these pollutants, hydrogen sulfide(H_2S) has attracted the most attention because of its severe corrosive property and relatively high comcentration(almost 1%).
