摘　　要：随着石油资源匮乏和工业不断发展,我国的石油对外依存度逐年增加。中低温煤焦油由于具有杂质含量低、烃类组分含量较多的特点,因此更适合作为石油的补充能源进行加氢改质生产各种燃料油;同时煤焦油加氢过程中产生的煤沥青具有高碳收率和高缩合度等特点,是制备高品质碳材料的优质原料。因此,对中国目前存在的6种煤焦油加氢技术和煤基沥青生产各种优质碳材料的研究现状做了相关讨论和概述。With the scarcity of oil resources and the continuous development of industry,China's dependence on foreign oil has been increasing year by year.Medium low temperature coal tar is more suitable for hydrotreating and upgrading to produce various fuel oils as a supplementary energy of petroleum due to its low impurity content and high hydrocarbon content;At the same time,the coal tar pitch produced in the coal tar hydrogenation process has the characteristics of high carbon yield and high degree of condensation,and is a high-quality raw material for preparing high-quality carbon materials.In this paper,six kinds of coal tar hydrogenation technologies and methods of producing various high-quality carbon materials from coal based asphalt in China were discussed and summarized.
