煤的结构对直接液化反应性影响的分析

系统地分析了煤的组成结构及液化前的预处理对直接液化反应性的影响,包括煤阶、岩相组成、各种矿物质及酸洗脱除、水分及烘干、孔隙性、物理结构及预溶胀、H/C比等,指出不同的工艺条件下它们对直接液化的影响是不同的。 Effects of composition and structure of coal and pretreatment before liquefaction on direct liquefaction reactivity are systematically analyzed,which include coal rank,maceral group,all types of mineral matters and their acidwashing deprivation,moisture and drying,porosity,physical structure and pre-swelling,H/C atomic ratio,etc. It is pointed out that under different process conditions their effects on direct liquefaction are different
