摘　　要：提高氢气利用率,降低生产成本已成为提升生产清洁燃料的加氢工艺装置效益的关键。通过分析低体积分数含氢气体的性质,结合TSA、PSA、深冷分离、膜分离等提浓工艺的特点、使用条件,对不同提浓工艺进行了技术经济分析,提出膜分离+PSA耦合工艺在提高低体积分数氢气有效利用方面的积极作用,为实现节能减排的目标提供参考。Improving utilization of hydrogen and reducing production cost have become the key of increasing the benefit of hydrogenation process device that produces clean fuel. Based on the analysis on the properties of low volume fraction hydrogen, the technical economical analysis is performed in combination with the characteristics and application conditions of TSA （Temperature Swing Adsorption）, PSA （Pressure Swing Adsorption）, cryogenic separation, membrane separation, etc. The positive role of combination of membrane separation and PSA in improving the efficient utilization of low volume fraction hydrogen is put forward, which can provide reference to achieve the purpose of energy saving and emission reduction.
