从煤阶(煤种)及煤的化学成分、煤中显微组分和煤中矿物质等方面阐述了液化煤的基本煤质要求,提出了液化煤的煤质评价指标。结合华东地区已有煤质数据,将液化煤资源划分为优质、亚优质、次优质和非优质液化煤四种类型,并确定了评价方法。概述了华东地区液化煤资源的总体构成和各含煤区液化煤资源类型。从总体构成看,华东地区以次优质液化煤为主,占72.15%,其次为优质液化煤,占25.36%。
The basic coal quality requirements of liquefied coal are expounded from the coal rank (coal type) and the chemical composition of coal, the microstructure of coal and the minerals in coal. The coal quality evaluation index of liquefied coal is put forward. According to the existing coal quality data in East China, the liquefied coal resources are divided into four types of high quality, sub-high quality, sub-high quality and non-high quality coal liquefaction, and the evaluation methods are determined. The general composition of liquefied coal resources in East China and the types of liquefied coal resources in each coal area are summarized. In terms of overall composition, sub-prime liquefied coal is dominant in East China, accounting for 72.15%, followed by high-quality liquefied coal accounting for 25.36%.
