摘要(Abstract)：

为提高变压吸附法制氢工艺性能，提出了一种热冲洗增强再生的八塔二十四步变压吸附工艺。该工艺采用活性炭和5A分子筛作为吸附剂，基于原料气中各组分在吸附剂上的吸附数据，利用商业软件Aspen Adsorption进行了模拟研究。通过数值模拟分析吸附塔内部温度、压力、组分等状态参数对工艺性能的影响，确定适宜的操作条件。研究结果表明，缓冲罐的引入显著提高了氢气的回收率和生产能力；热冲洗则增强了吸附塔的再生效率，从而提升了氢气产品的纯度，最佳冲洗气温度为333 K。与传统工艺相比，热冲洗增强再生制氢工艺将纯度由98.781 6%提升至99.345 6%、回收率由85.36%提升至86.01%，生产能力和能耗分别为2.05 mol·（kg_(ads)·h)~(-1)和16.80 kJ·mol~(-1)。
