将过渡金属化合物负载到高比表面载体上可以得到具有工业化前景的乙烯 乙烷分离吸附剂,采用柱动态法研究了氧化处理和负载铜(Ⅰ)改性活性炭的乙烯 乙烷吸附分离性能,结果表明,以表面氧化改性活性炭为载体,CuCl为活性组分的负载型吸附剂较活性炭直接负载CuCl吸附剂具有较大的乙烯吸附容量和选择性,AC H2O2 CuCl吸附剂的乙烯吸附容量为21.2mL(STP) g,乙烯 乙烷分离系数达到8.7,其原因是活性炭氧化改性后,表面羧基基团明显增多,使CuCl与活性炭表面结合力加强,改善了其分散状态,提高了利用率。
Ethylene oxide separation adsorbents with industrialized prospect can be obtained by loading transition metal compounds onto high surface area carriers. The column dynamic method was used to study the adsorption and separation of ethylene and ethane by oxidative treatment and copper (Ⅰ) modified activated carbon. The results The results showed that the adsorbent with CuCl as the active component and the CuCl adsorbent with CuCl as the active component had greater ethylene adsorption capacity and selectivity than the activated carbon loaded CuCl adsorbent. The ethylene adsorption capacity of ACH 2 O 2 CuCl adsorbent was 21.2 mL (STP) g, and the separation factor of ethylene and ethane reached 8.7. The reason for this is that the carboxyl groups on the surface of the activated carbon are obviously increased after the oxidization of activated carbon, the binding force between the surface of the activated carbon and CuCl is enhanced, the dispersion state is improved and the utilization ratio is increased.
