摘　　要：液体燃料广泛应用于交通、物流和生活等行业,然而液体燃料的生产严重依赖石油。我国石油资源相对贫乏,石油对外依存度高达60%。为减少对石油的依赖,我国正积极开发石油替代资源,特别是油页岩和煤炭。但迄今少有文献报道对油页岩与煤路线生产液体燃料过程进行全面的技术经济分析和比较。本文通过对油页岩制油和煤制油分别进行建模和模拟,根据模拟从能效、投资和成本等方面对这两种路线进行分析和比较。结果表明油页岩制油的能效比煤制油低5个百分点,因为油页岩制油的原料利用率低,产品收率低。经济方面,油页岩制油的固定投资为63.34元/GJ,相比煤制油节省70%,因为油页岩制油流程短,设备结构简单。但油页岩制油的原料消耗大,生产1t液体燃料消耗24.5t油页岩,所以其成本相比煤制油仅节省6%。Liquid fuels are widely used in transportation,logistics,and lives. However the production is heavily dependent on oil. In China oil resources are relatively scarce. Import dependence is as high as 60%. To reduce dependence on oil,the production of liquid fuels from alternative energy resources,especially from oil shale and coal is increasing in China. However,few literatures can be found for analysis and comparison of oil shale-to-liquid（STL） and coal-to-liquid（CTL） processes. This paper models and simulates a STL process and a CTL process. Based on the models,analysis of the two processes is made from energy efficiency,capital investment,and production cost. Energy efficiency of STL process is lower by about 5%,compared to CTL process. This is because STL process has lower utilization rate of raw material and product yield. Total capital investment of STL process is 63.34 CNY/GJ,70% lower than that of CTL process,because this process has simple flow scheme and lower equipment investment. However,raw material consumption of STL process is much higher. Producing 1t liquid fuels consumes 24.5t oil shale. This makes production cost of STL process only lower by 6% compared to CTL process.
