烟气直接催化还原脱硫研究进展

Investigation Progress of Direct Catalytic Reducing Desulfurization of Flue Gas

烟气直接催化还原脱硫是一种非常重要的、很有吸引力的烟气脱硫 (FGD)技术 ,近年来受到了普遍的关注。从CO和H2 两类还原剂出发 ,综述了烟气直接催化还原脱硫的主要研究成果。重点讨论了有关催化剂的性质和反应机理。最后 ,论述了几种重要方法的发展趋势。

The direct catalytic reducing desulfurization of flue gas is a very important and attractive flue gas desulfurization (FGD) technique and close attention is paid popularly in recent years. Starting from CO and H 2 as two reducing agents, the main investigation merits of FGD by direct catalytic reduction are described. The paper focuses the discussion of the catalyzer property and reaction mechanism. Finally,the development trend of several important methods is discussed.
