| 摘 要： | 通过自由基溶液聚合制备了聚丙烯酸，使其与1,1,3,3-四甲基胍中和反应制得聚丙烯酸四甲基胍(PTMGA)，利用模拟的工业装置，研究了PTMGA水溶液在不同温度和烟气条件下吸收-解吸SO2的性能. 结果表明，PTMGA水溶液对SO2具有较好的吸收-解吸性能及选择吸收性能. 当吸收温度40℃、烟气中SO2浓度2%或4%(j)时，PTMGA水溶液吸收SO2效率大于97%，解吸效率大于40%，且低温利于吸收，高温利于解吸.

| Abstract: | The polyacrylic acid with different molecular weights was synthesized by free radical solution polymerization, then the poly(1,1,3,3-tetramethylguandium acrylate) (PTMGA) was obtained through neutralizing PAA with 1,1,3,3-tetramethylguanidine. The effects of temperatures and concentration of flue gas on absorption and desorption properties of SO2 by PTMGA solution were investigated in the current industrial processes. The results show that the title PTMGA solution is a kind of good absorption-desorption and selective absorption agent to SO2. The absorption efficiency of PTMGA aqueous solution is higher than 97%, and the desorption efficiency more than 40% when temperature is 40℃, and SO2 concentration of flue gas 2% or 4%(j). Furthermore, the PTMGA solution tends to absorb SO2 at low temperature, and desorb SO2 at high temperature. |
