摘要
对Cu(I)-活性炭吸附剂净化合成氨原料气中微量CO进行了研究。这种吸附剂对CO具有良好的选择性,可使吸附器出口残余CO含量达到0.1ppm。考察了吸附及脱附条件对吸附剂性能的影响以及它的稳定性。进行了中试实验,净化度为出口CO及CO2的总和小于5ppm,完全满足合成氨生产要求的两者之和<10ppm的需要。
A study is carride out on removal of small amount of carbon monoxide from synthesis gas for ammonia production via adsorption on Cu(I) active carbon adsorbent that has high selectivity for carbon monoxide.After adsorption,the residual CO in the effluent gas from the adsorber is 0.1 ppm.The adsorption and desorption conditions on the properties of the adsorbent is investigated,and the stability of this type of adsorbent examined.A pllot plant test is conducted and the results show that the total amount of CO and CO 2 in the effluent gas from the adsorber is below 5 ppm,well satisfying the requirement of ammonia synthesis(<10 ppm).The feasibility of this method is confirmed as it is more energy saving compared to methanation.
