摘要
介绍了煤直接和间接液化生产燃料油技术的发展历程及现状,并比较了煤直接和间接液化的优缺点。煤直接液化投资较低,产物主要由环状烃组成;煤间接液化投资较高,产物主要由链状烃组成;两种方法生产的燃料油性质互补,通过调合可以得到满足《世界燃油规范》Ⅱ类以上标准的柴油产品。
Development course and the status quo of direct and indirect coal liquifaction to produce fuel oil are expounded. Advantages as well as disadvantages of coal direct liquifaction and indirect liquifaction have been compared . The investment of coal direct liquifaction is lower and its product is mainly composed of cyclic hydrocarbons, while the investment of coal indirect liquefaction is higher and the product mainly consists of paraffin. Properties of the two products compensate each other and the diesel, which meets the standard of 'Specification of Fuel Oil' Ⅱ class can be obtained by blending the two products.
