摘要
对文题的吸附平衡、吸附及脱附的工艺条件进行了考察。用Ｌａｎｇ－ｍｕｉｒ－Ｆｒｅｕｎｄｌｉｃｈ公式关联了吸附平衡数据。根据吸附的性质，关联了吸附穿透曲线，解释了床层动力学现象。结果表明，利用此技术可将氢气中ＣＯ体积含量从２×１０￣（－６）～１６×１０￣（－６）降至１×１０￣（－６）以下，吸附剂单位处理量达６×１０￣（－３）ｍ￣３／ｇ以上（标准状况下气体体积）。同时，吸附剂再生容易，经１２０℃处理，即可脱附完全。该吸附剂经多次循环，性能稳定，具有一定工业应用价值。
The purification of hydrogen for TDI was studied.The CO in hydrogen was re-quired to be reduced by adsorption to lower than 1×10￣(-6).The active carbon supported cop-per,which can selectively adsorb CO,was used as adsorbent.The adsorption equilibrum ,operation conditions of adsorption and dessorption were studied too. It is showed that this pro-cess can reduce the concentration of CO in hydrogen lower than 1×10￣(-6). The high through-put capacity and good dessorption property of the adsorbent will make it more useful in commerical.
