摘　　要：使用SIFSIX-3-Ni(MOF)作为吸附剂,应用Aspen adsorption软件建立双床6步工艺流程模型,对CHF_(3)/N_(2)混合气体变压吸附(PSA)提纯CHF_(3)的过程进行了研究。分析了吸附压力、进料流量、吸附时间、均压时间、降压时间以及真空度等主要工艺参数对φ(CHF_(3))和回收率的影响,通过工艺模拟,当吸附压力1.5 bar,进料流量0.6 m^(3)·h^(-1),吸附时间165 s,均压时间22 s,逆放时间95 s,真空度0.1 bar条件时,φ(CHF_(3))达到99%以上,回收率达到90%以上。The adsorption column was filled with SIFSIX-3-Ni(MOF)as the adsorbent.The purification process of CHF_(3) from CHF_(3)/N_(2) mixture by pressure swing adsorption(PSA)was simulated by a two-bed six-step model using Aspen adsorption.The effects of adsorption pressure,feed flow rate,adsorption time,pressure equalization time,blow down time and vacuum degree on the purity and recovery of CHF_(3) were studied.The optimum process simulation conditions have been achieved when the adsorption pressure,feed flow rate,adsorption time,pressure equalization time,blow down time and vacuum degree are 1.5 bar,0.6 m^(3)·h^(-1),165 s,22 s,95 s,0.1 bar,respectively.Under this condition,the purity of CHF_(3) is above 99%and the recovery is above 90%.
