摘要：

变压吸附(PSA)作为一种有效的气体分离与净化技术，具有工艺操作灵活、自动化程度高等优点。但通过变压吸附的方式回收氢气会存在一定的氢气损失，其损失主要在吸附剂的再生阶段。降低PSA氢气损失率可通过延长吸附时间或减少再生阶段的氢气损失来实现。在保证产品质量合格的情况下，稳定优化PSA操作参数，合理设置运行时间,能充分发挥吸附剂的作用，尽可能降低PSA氢气损失率，提高氢气收率。

Abstract:

Pressure swing adsorption (PSA), as an effective gas separation and purification technology, has the advantages of flexible process operation and high degree of automation. However, the recovery of hydrogen through PSA will result in certain hydrogen losses, mainly in the regeneration stage of the adsorbent. The hydrogen loss rate of PSA can be reduced by extending the adsorption time or reducing the hydrogen loss during the regeneration stage. Under the premise of ensuring product quality, stabilizing and optimizing PSA operation parameters and setting the operating time within a reasonable range are necessary to fully utilize the role of the adsorbent and minimize the hydrogen loss rate of PSA while improving hydrogen yield.

Key words: pressure swing adsorption; hydrogen loss rate, process optimization
