活性炭负载氯化铜吸附CO的研究

ADSORPTION OF CO BY ACTIVE CARBON-SUPPORTED CUPRIC CHLORIDE

<正> 利用Y型分子筛负载Cu(Ⅰ)吸附CO的方法虽早有报道,但这种吸附剂与CO的结合能力相当强,即使在室温下减压到0.01Pa时也不容易脱附,而且在CO的分压大于1.333×10~3Pa时,其吸附量就达到饱和。近几年来。

Active carbon-supported cupric chloride as adsorbent for CO was prepared by impreganting active carbon with aqueous CuCl_2, followed by drying at 120℃, and heating in N_2 at 300℃ for 1h.The adsorbent rapidly adsorbed CO from N_2-CO mixture under 0.1 MPa at room temperature. All of the adsorbed CO was readily desorbed either by evacuation at room temperature or by heating to 120℃ under 0.1 MPa. When the load of CuCl_2 is 1.5 mmol/gAC, the equilibrium amount of adsorbed CO for this adsorbent was 1.14 mm(?)l/g at, 20℃ under a CO partial pressure of 0.09 MPa, which was larger then that of a similar adsorbent. The CO adsorption capacity was attributed to CuCl formed by the reduction of CuCl_2 by the support.
