以SBA-15为载体,氯化铜为铜源,葡萄糖为还原剂,采用等体积浸渍法制备络合吸附剂,并将该吸附剂用于乙烯乙烷吸附分离性能测试,考察了铜源与葡萄糖的摩尔比、焙烧温度对吸附性能的影响,确定最佳工艺制备条件:n(Cu Cl2·2H2O)∶n(葡萄糖)=2∶1,焙烧温度为350℃。测试杂质气体CO、H2的吸附性能,最后通过FT-IR表征对葡萄糖还原氯化铜机理进行初步探讨,结果表明,葡萄糖中的醛基对还原起主要作用。
SBA-15 as a carrier, copper chloride as a copper source, glucose as a reducing agent, using an equal volume impregnation complex preparation of adsorbent, and the adsorbent for the adsorption of ethylene ethane separation performance test investigated the copper source and Glucose molar ratio, calcination temperature on the adsorption performance, to determine the optimum preparation conditions: n (Cu Cl2 · 2H2O): n (glucose) = 2: 1, calcination temperature of 350 ℃. The adsorption properties of impurity gases CO and H2 were tested. Finally, the mechanism of glucose reduction of copper chloride by FT-IR was studied. The results showed that the aldehyde groups in glucose played a major role in the reduction.
