摘要
填埋气体(LFG)作为可再生的清洁能源,对其进行回收利用是非常重要的。变压吸附作为一种气体分离技术,能较好地将CH4与CO2分离。文章对填埋气体的变压吸附进行了小试试验,根据不同操作条件下产品气中甲烷浓度和甲烷回收率来确定最佳操作条件,从而为填埋气体变压吸附的中试试验提供一定的理论依据。
Landfill gas could be used as the renewable and clean energy,and it is very important to be utilized.Pressure swing adsorption（PSA） is a new technology for the separation of the mixtures,and it could remove the CO2 content from the CH4 rich landfill gas.In this paper,the small-scale experiment on the LFG purification with PSA was studied.The optimum condition has been determined according to the concentrations and recovery rates of methane under various operation conditions.It could provide the theoretic reference for the pilot-scale experiment of the landfill gas.
