摘　　要：在安全性和经济性分析的基础上,研究了生物质热解液化实验的尾气循环利用。分别在尾气循环使用和不循环使用两种状态下进行热解实验,收集尾气,色谱分析后发现其主要组分无差别,但主要组分含量有差别;通过与理论分析的循环尾气组分含量比较,判断不可冷凝气体对热解反应的影响,并对生物质油的产收率和成分进行分析,得到生物质液化过程中尾气循环使用的方法和可行性。Based on the safety and economy analysis, the tail-gas recirculation in biomass pyrolysis liquefaction plant was investigated. The pyrolysis liquefaction experiments were conducted with or without the tail-gas recycling for comparison. The tail-gas was collected and then analyzed by gas chromatography. Results indicated that the major composition of the tail-gas is the same under the two different pyrolysis conditions, while the contents are different. The influence of non-condensate gas, such as CO, CO2 and CH4, to the biomass pyrolysis was theoretically analyzed, and the yield and composition of the produced bio-oil was evaluated. It is suggested that the tail-gas recirculation in biomass pyrolysis liquefaction plant is reasonable and feasible.
