摘要
目前我国液体燃料严重短缺 ,环境污染形势也十分严峻。以煤气化为核心的多联产能源系统是解决我国未来能源可持续发展的一个重要方向。以煤为原料经“一步法”费托合成生产液体燃料 ,同时与燃气 -蒸汽联合循环结合联产发电是多联产系统的一种方案。文中综述了国外以煤、天然气或生物质为原料生产液体燃料的流程和经济性 ,论述了费托合成采用“一步法”流程、生产液体燃料同时与燃气 -蒸汽联合循环结合联产发电是降低成本的有效方法。图 4表 2参 1
China is deadly short of liquid fuels, and environmental pollution is also very serious now. China's energy system is not sustainable with existing technologies being used. Polygeneration based on coal gasification is a promising sustainable energy strategy. One of the polygeneration projects is to convert coal to liquid fuels via Fischer Tropsch synthesis and co produce electricity by Combined Cycle. After referring the process and economics analysis of wordwide research on F T, it shows that an efficient way for lowering down the capital investment and products' cost is to apply the once through configuration to Fischer Tropsch synthesis and co producing electricity.
