随着合成气制备工艺的迅速发展，提纯合成气中的有用成分应用于工业生产愈显重要。本研究将含有 CO、H2、CH4、H2O、CO2及少量烃类的粗合成气经过变压吸附提纯后作为与丁烯反应生产2-丙基庚醇的原料气。该变压吸附过程包含2段，第一段采用装载硅胶和活性炭的复合床层用以脱去除 H2与 CO 以外的其他气体获得较纯的合成气；第二段采用装载 NA 型络合吸附剂的床层用以分离 H2和 CO。利用 Aspen Adsorption 软件对变压吸附过程进行了模拟。模拟结果表明，采用该2段变压吸附过程可以获得纯度为99.9%的 H2用于烯醛加氢反应，同时由二段吸附过程的解吸气可配出 H2：CO=1：1的混合气用于丁烯羰基化反应。

It is more and more important to purify useful components from syngas for industrial production with the rapid development of the syngas preparation technology. In this study, the crude syngas consisted of CO, H2, CH4, H2O, CO2 and a small amount of hydrocarbon gas was purified by the pressure swing adsorption (PSA), and the purified gas was used as the row gas in a reaction with butylenes for the production of 2-propyl heptanol. This PSA process includes two stages: a layered bed loaded silicone and activated carbon used as adsorbents to removal all the compositions except H2 and CO in the first stage; a single bed loaded NA used as adsorbents to separate H2 and CO in the second stage. PSA process was simulated by Aspen Adsorption software. Simulation results indicate that after these two stages of PSA, the H2 with the purity of 99.9% can be obtained for the hexenal hydrogenation reaction. On the other hand, the mixture gas for the carbonylation of butylenes can be obtained by adding the purified H2 to the desorbed gas from the second stage obtains.
