摘　　要：氢气纯化变温吸附装置中分子筛再生采用原料气再生,正常吸附状态下分子筛吸附层能够保证用户对氢气露点的要求,分子筛吸附层吸满水后再生切换时露点在很短时间内急剧升高,本文以QCYZ-XX型装置为例研究探讨通过状态切换参数的调整来改善产品气的露点波动,从而满足用户使用要求。Molecular sieve regeneration of temperature swing adsorption use the raw gas in hydrogen purification unit. Molecular sieve adsorption layers in normal adsorption states can guarantee the user requirements for hydrogen dew point. When molecular sieve adsorption layer is filled with water and the state of absorption regeneration switches, the dew point will decline sharply in a very short time. This article explores to improve the dew point fluctuating of output gas by adjusting parameter of state switch for example QCYZ-XX equipment and meet the requirement of the user to hydrogen.
