Coal due to its relatively large quantities and wide distribution worldwide has generated renewed interest in research and development with the aim of establishing coal conversion technologies that are technically reliable, environmentally and economically feasible. It has proved to be a prominent energy source in emerging markets with increasing energy demand by accounting for the largest increase in the demand of energy amongst all other energy sources. Furthermore, with its higher mesophase content, coal tar is an appropriate raw material for precursors in the production of carbon fiber. However, whenever a material is put to use, it is important to be able to associate its properties to the behavioral characteristics during a conversion process so as to have a basis for opting for the material in a given process or adjusting the operating conditions in order to optimize the material utilization. Therefore, as with any other material, it is important to be able to relate the properties of coal to its utilization. A review was carried out on the influence of coal properties on four main utilization technologies: gasification, carbonization, liquefaction and carbon fibre production. Among several properties rank, type, mineral matter content, distribution of trace elements, structural composition and pore structure were found to be most influential on the behavior of coal during conversion processes.

煤炭由于其相对较大的数量和广泛的分布范围而在全世界引起了人们对研发的新兴趣，其目的是建立技术上可靠，环境和经济上可行的煤炭转化技术。事实证明，在所有其他能源中，能源需求增长最大，它是新兴市场中能源需求不断增长的主要能源。此外，煤焦油具有较高的中间相含量，是碳纤维生产中前体的合适原材料。但是，无论何时使用某种材料，重要的是能够将其属性与转换过程中的行为特征相关联，以便为在给定过程中选择材料或调整操作条件以优化材料利用率提供基础。因此，与任何其他材料一样，重要的是能够将煤炭的性质与其利用联系起来。综述了煤炭性质对四种主要利用技术的影响：气化，碳化，液化和碳纤维生产。在转化过程中，煤的性能等级，类型，矿物质含量，微量元素分布，结构组成和孔结构等对煤的行为影响最大。与任何其他材料一样，重要的是能够将煤炭的性质与其利用联系起来。综述了煤炭性质对四种主要利用技术的影响：气化，碳化，液化和碳纤维生产。在转化过程中，煤的性能等级，类型，矿物质含量，微量元素分布，结构组成和孔结构等对煤的行为影响最大。与任何其他材料一样，重要的是能够将煤炭的性质与其利用联系起来。综述了煤炭性质对四种主要利用技术的影响：气化，碳化，液化和碳纤维生产。在转化过程中，煤的性能等级，类型，矿物质含量，微量元素分布，结构组成和孔结构等对煤的行为影响最大。
