摘　　要：为探究传统制氢工艺与新型制氢工艺的经济性与环保性,采用技术经济分析和生命周期评价(LCA)的方法对煤制氢过程和生物质制氢过程产生的温室气体(GHG)排放和能源消耗(EC)进行分析,其中,技术经济分析包括总资本投资(TCI)和生产成本,系统生命周期边界包括原料生产与运输、合成气体的产生、氢净化、氢的运输和应用。研究结果表明:与煤制氢工艺相比,生物质制氢工艺的原料消耗和总资本投资大,但生产成本低,排放的温室气体少;生物质制氢工艺的能耗与煤制氢工艺的能耗相比低75.4%,温室气体排放量比煤制氢过程的排放量低89.6%。In order to explore the economics and environmental protection of the traditional hydrogen production process and the new hydrogen production process,greenhouse gas(GHG)emissions and the energy consumption(EC)in the process of biomass-to-hydrogen(BTH)and coal-to-hydrogen(CTH)were analyzed by techno-economic analysis and life cycle analysis(LCA).Techno-economic analysis included total capital investment(TCI)and production cost.The production and transportation of raw materials,the generation of synthetic gas,hydrogen purification,the transportation and application of hydrogen were included in the system life cycle boundary.The results show that raw material consumption and total capital investment of the BTH process are larger,but the production cost and GHG emissions are lower compared with those of the CTH process.The EC value of BTH process is 75.4%lower than that of CTH process.The GHG emission of BTH process is 89.6%lower than that of CTH process.
