摘　　要：在温度30～90℃、时间1～6 min、绝对压力700～100 Pa范围内,单因素考察时,其余2个因素依次选取3 min,400 Pa,60℃,得到固态胺纤维(SAF)真空解吸CO2的效率分别为:16.63%～85.47%,32.11%～72.30%,46.42%～78.02%。通过正交实验,得到各因素对反应影响的显著性依次为温度、绝对压力及时间。在实验室条件下,考虑到应用装置寿命、能耗、体积及重量,较优反应条件取温度70℃,再生时间2.5 min,绝对压力300 Pa,此时再生效率为82.32%。In the temperature range of 30 - 90 ℃ ,time of 1 - 6 min, absolute pressure of 700 - 100 Pa, the regeneration efficiency of solid amine fiber（SAF）desorption of CO2 by vacuum were 16. 63% -85.47% , 32. 11% - 72. 30% , 46. 42% - 78.02% respectively, as single factor was investigated, and the rest took 3 min ,400 Pa,60 ℃ in turn. Through the orthogonal experiment, the significance sequence according to the effect of various factors on the reaction was as follows：temperature, absolute pressure, time. Under laboratory conditions, considering the lifetime, energy consumption, size, and weight of the application device, the optimum conditions of solid amine fiber regeneration by vacuum were：70 ~C ,2. 5 min,300 Pa,the regeneration efficiency was 82. 32% simultaneously.
