| 中文摘要 |
| 一种含有双羟基层状结约的粘土材料(Stratified Deuble Hxdrokides简称SDH)在高温下对SO2具有良好的吸附性能。本实验用合成的SDH材料来研究脱硫反应的性能。实验结果表明,SDH对SO2的吸附容量大,吸附速率高,选择性好。通过对不同温度下SO2吸附速率的研究,得出ZnAl和ZnMgAl类SDH的最佳吸附温度为750℃,NiAl类SDH的最佳吸附温度为700℃吸附选择性随温度的升高而增大。经再生后的SDH材料吸附速率在前10min几乎不变,吸附容量下降不大。 |
| 英文摘要 |
| An experimental study was conducted on the desulfurization characteristics of a synthesized class of double hydroxyl stratified clays as a desulfurizer of high temperature flue gases. The results show that after roasted at a high temperature the materials had a higher capacity of desulfurization,a higher rate of SO2 adsorption,and a higher selectivity to SO2.By studying the reaction rates at different temperatures,the optimum temperature for each of the stratified double hydroxides(SDH) was found to be 700℃ for NiAl SDH and 750℃ for both ZnAl SDH and ZnMgAl SDH. The selectivity to SO2 was found to increase with the temperature rising from 500℃ to 750℃. During the first 10 minutes after a regeneration,the SDHs had essentially an unchanged reaction rate and an insignificantly decreased capacity of desulfurization. |
