摘　　要：面对能源资源日益短缺的局势,油页岩的开发与利用日益得到各界的重视。目前油页岩以干馏炼油为主,很少有对油页岩综合利用过程进行技术经济分析的研究。本文建立油页岩综合利用过程各基础过程的单元模型,对物流和能量流展开流程模拟和技术经济分析。结果表明,过程技术性能与能效较合理区域为:干馏温度525℃,空气与水蒸气之比为1.13。与单纯炼油过程相比,综合利用过程的投资利润率从13%提升到16%,投资回收期从7.5年缩减到6.3年。To relieve the shortage of oil, exploration of oil shale attracts increasingly attention of different countries, especially China. However, there are few systematic studies on comprehensive utilization of oil shale. This paper models a comprehensive utilization process and analyzes its techno-economic performance, compared to a conventional pyrolysis process. Appropriate retorting temperature and air to steam ratio are selected according to oil productivity and electricity generation. The comparison suggests that the comprehensive process is more economically competitive： the return on investment increasing from 13% to 16% and the payback period decreased from 7.5 years to 6.3 years.
