【摘要】 研究了以大同烟煤为原料制取的脱硫剂的再生性能。结果表明,这种脱硫剂的再生性能稳定,经5次重复再生试验,对SO₂的吸附量基本恒定。在常温吸附时,最佳脱附温度范围为120～140℃,用变温流程试验表明,在重复吸附—脱附过程中,从吸附柱排出的尾气内含SO₂浓度值可达35％。更多还原

【Abstract】 Regenerative characteristics for manufacture of desulfurizing substance from Datong bitumen coal were studied. The results showed that regenerative characteristics of desulfurizing substance were stable. Through repeatable regenerative tests in five time, the SO2 adsorptive capacity was identity basically. When the adsorption was carried out in room temperature, the best range of desorptive temperature was 120-140 ℃ The results by temperature swing tests showed that the SO2 concentration in the tail gasfrom the adsorptive——desorptive processes was provided for better conditionof recovery sulphur.更多还原
