在我国，油页岩的常规利用主要集中在油页岩干馏生产页岩油和燃料气，以及油页岩燃烧发电。石油价格的上涨和重工业的发展，使这些常规的利用设施在能源市场上变得不可替代。针对桦甸油页岩的特点和能源现状，提出了桦甸油页岩综合利用的新体系。该系统包括三个子系统：干馏子系统，其中粗油页岩（8-80 mm）干馏为页岩油、烃气和油页岩半焦;燃烧子系统，将油页岩半焦和细油页岩（0-8 mm）的混合燃料送入循环流化床（CFB）炉中燃烧，以产生高压蒸汽，通过传统的蒸汽-电力模式用于供热和发电，以及灰处理子系统，利用循环流化床炉产生的油页岩灰生产建筑材料。通过对桦甸油页岩综合利用系统（处理能力为2.6 × 10（6）t/a）的经济性分析，表明该系统在经济效益和产品类型上具有油页岩综合利用的优势。(c)2006爱思唯尔有限公司保留所有权利。
In China, the conventional utilization of oil shale is concentrated mainly on retorting oil shale to produce shale oil and fuel gas, and burning oil shale to generate electricity. The growth of petroleum price, and the development in heavy industry, make these conventional utilization facilities become unavailable on the energy market. In this paper, a new comprehensive utilization system is recommended for the future use of Huadian oil shale, based on the current status of energy and the characteristics of oil shale. The system involves three subsystems: retort subsystem, where coarse oil shale (8-80 mm) is retorted to shale oil, hydrocarbon gases and oil shale semicoke; combustion subsystem, where the mixture fuel of oil-shale semicoke and fine oil shale (0-8 mm) is fed to a circulating fluidized bed (CFB) furnace to burn, in order to generate high-pressure steam which is used to supply heat and generate electricity via a traditional steam-electric power mode; and ash processing subsystem, where oil shale ash from the CFB furnace is utilized to produce building materials. A comprehensive utilization system with handling capacity of 2.6 x 10(6) t/a Huadian oil shale is economically analyzed, showing that it can advantage oil shale utilization in the economic efficiency and the product type.
