【摘要】 以煤质活性炭为载体,氯化铜为铜源,甲酸铜为还原剂,采用热分散法制备CuCl-AC吸附剂。通过变压吸附法（PSA）测量该吸附剂对乙烯乙烷吸附分离性能。考察了铜担载量、焙烧温度、焙烧时间等因素的影响。结果表明,通过甲酸铜还原法制备CuCl-AC吸附剂,最佳制备工艺条件为:CuCl₂担载量为4mmol,Cu（HCOO）₂担载量为4mmol,焙烧温度300℃,焙烧时间4 h。在30℃,0.5MPa的条件下,它对乙烯的吸附量为32.39 mL/g,分离系数为2.47,对变压吸附具有很好的分离应用前景。更多还原

【Abstract】 Complexing adsorbent is synthesized by the heat dispersion method with coaly activated carbon as carrier,CuCl₂·2 H₂O as copper source and Cu（ HCOO）₂·4 H₂O as reduction agent. The separation performances of this adsorbent for ethylene-ethane system are studied in a pressure swing adsorption device. The influences of the loading amount of copper,calcination temperature,calcination time on the adsorbent are investigated. The results showed that the optimal synthesis parameters for the CuCl adsorbent manufacture by copper formate reduction method are: n（ Cu（ HCOO）₂·4 H₂O） = 4 mmol,n（ CuCl₂·2 H₂O） = 4 mmol,calcination temperature = 300℃,calcination time = 4 h. The adsorption amount of ethylene on this copper loading adsorbent is 32. 39 mL/g and the separation factor is 2. 47 at 30℃ and 0. 5 MPa,which has a promising separation application for pressure swing adsorption.更多还原
