【摘要】 用共沉淀法制得的铜锰脱硫剂是一种新型的高温煤气脱硫剂。本文从硫化氢浓度、脱硫温度、空速和脱硫剂的粒度几个方面考察了它们对脱硫剂的影响，可以看出该脱硫剂的反应活性与硫化氢浓度基本上成正比，但与脱硫温度的关系较为复杂。在低于６００℃时脱硫剂的活性基本上随温度升高而增加，而在６００℃以上的温度时则有所波动。空速对其反应活性的影响类似于硫化氢浓度的影响。该脱硫剂还具有脱硫精度高，硫容量大等特点。更多还原

【Abstract】 Copper manganese oxide sorbent prepared by coprecipitated is identified as a novel coal gas desulfurization sorbent at high temperature In this study the effects of H 2S concentration, desulfurization temperature, gas space velocity and the particle size on desulfurization reactivity and sulfur capacity of CuMnO sorbents are investigated It is found that desulfurization reaction rate and gas space velocity seem to be in direct proportion to the concentration of H 2S But the relationship between reaction rate and desulfurization temperature is not so simple When the desulfurization temperature is below 600℃, the reaction rate is speeded up with increasing temperature, while it is opposite at high temperature After desulfurization, the H 2S concentration in exit gas can be reduced to 1￣2ppm, therefore CuMnO sorbents can meet the requirement in gas quality for IGCC process更多还原
