摘要
通过对吸附剂的吸附等温线的数学模拟,获得了该吸附的Langmuir等温模型,由此计算出吸附剂再生的特征温度为118℃。在单塔吸附装置上进行变温吸附(TSA)法脱除氢气中微量CO实验研究,比较了室温下氢气中CO体积分数为0.001%和0.015%时的穿透曲线和吸附传质区特征。理论计算的特征温度与实验获得的较佳再生温度相吻合。
The Langmuir adsorption isotherm model was obtained by mathematical simulation of the equilibrium isotherm of the monoxide carbon adsorbent, and the characteristic temperature for the regeneration process of the adsorbent in the temperature swing adsorption cycle was calculated to be 118℃ by this model. An experimental study on the removal of trace carbon monoxide from the hydrogen feed gas by temperature swing adsorption （TSA） was made in a one-column system. The breakthrough curves and the char- acteristics of mass transfer zone at ambient temperature for the feed gases with carbon monoxide volume fraction of 0.001% or 0.015% were compared, The calculated characteristic temperature was in agreement with the optimum regeneration temperature obtained from the experiments.
