摘　　要：采用甘肃临泽产凹凸棒石(ATTP)与CaO复合,制成了具有吸附催化作用的脱硫剂。实验主要研究了CaO含量、脱硫剂含水率、床层温度对脱硫效率的影响。试验结果表明,CaO含量为20%～30%,脱硫剂含水率在20%～30%、床层温度为常温时,凹凸棒石基新型脱硫剂脱硫效果最好,硫容最大可达17.12%。Attapulgite（ATTP）, produced in Gansu Linze, and metal oxides CaO, which was used as a conventional desulfurizer, were used to prepare a kind of new desulfurizer. The influences of content of CaO, water content rate of desulfurizer, bed temperature on desulfurization had been studied. As a rusult, the sulfur tolerance of the desulfurizer reached 17.12%, when CaO is about 20%-30%, water content rate of desulfurizer is about 20%-30% and bed temperature is nomal.
