煤直接液化产品的组成、特性及应用

从产品组成方面阐述了煤直接液化油品与石油基油品的差异,指出煤直接液化油品主要以环烷烃为主,是非常理想的环烷基基础油,从而决定了其在特殊领域的应用潜力。煤直接液化油品具备高密度、高热容、高热安定性、高热值、高环烷烃、凝点低、低硫、低氮、低芳烃等特性,可作为军用及航空航天领域特种燃料,主要包括煤基大比重喷气燃料、煤基低凝点柴油及煤基航天煤油。最后指出,应充分发挥煤直接液化油品的优点,将有利于减轻我国对石油资源的依赖,保障战略能源安全。

Composition,characteristics and application of direct coal liquefaction products

This paper elaborated the differences between direct coal liquefaction oil and petroleum based oil from the aspect of product composition.It was pointed out that the direct coal liquefaction oil was mainly naphthenic,which was a very ideal naphthenic base oil,which determined its application potential in special fields.Direct coal liquefaction oil with the characteristics of high density,high heat capacity,high thermal stability,high calorific value,high cycloalkanes,low freezing point,low sulfur,low nitrogen and low aromatics,could be used as military and aerospace special fuels,mainly including coal-based large proportion jet fuel,coal-based low freezing point diesel and coal-based aerospace kerosene.Finally,it was pointed out that giving full play to the advantages of direct coal liquefaction oil products was conducive to reduce China's dependence on petroleum resources and ensure strategic energy security.
