CO在负载CuCl的Cu（Ⅰ）Y型沸石分子筛吸附剂上的吸附分离

Selective Adsorption Separation of CO on Adsorbent of Cu(Ⅰ)Y Type MS Carrying CuCl

实测了具有不同ＣｕＣｌ负载量（０－２．０ｍｍｏｌ／ｇＭＳ）的Ｃｕ（Ⅰ）Ｙ型沸石在７５℃、１００℃和１００ｋＰａ、２００ｋＰａ下对ＣＯ、ＣＯ＿２和Ｎ＿２的（相对）吸附量和吸附分离因数，并提出了ＣＯ在该吸附剂上的吸附平衡模型。结果表明，负载１．２－１．８ｍｍｏＬＣｕＣｌ／ｇＭＳ的Ｃｕ（Ⅰ）Ｙ型沸石吸附剂较未负载ＣｕＣｌ的Ｃｕ（Ⅰ）Ｙ型吸附剂对ＣＯ／ＣＯ＿２和ＣＯ／Ｎ＿２的吸附分离因数有较大的提高，可适用于工业废气中ＣＯ的ＴＳＡ和ＰＳＡ分离。

The adsorption amounts and separation factors of CO/CO_2/N_2 on Cu(Ⅰ)Y type MScarrying different amounts of impregnated CuCl were determined at 75℃,100℃ and under100kPa,200kPa Meanwhile,the adsorption equilibria models of CO on this adsorbent wereproposed. The results show that the adsorptive separation factors of CO/CO_2 and CO/N_2 onCu(Ⅰ)Y type MS impregnated with 1.2-1.8mmol CuCl/gMS are much higher than those onCu(Ⅰ)Y type MS with no impregnated CuCl.This adsorbent may be used not only for TSAseparation,but also for PSA separation Which is more important。
