摘要

矿物是在煤中发现的微观可识别的有机实体。根据其光学性质，可将其分为三大类:脂质组、镜质组和惰质组。反应性显微物质，镜质组和脂质组，在焦炭形成过程中对煤的热塑性性质负责。还发现这些矿物可用于制造碳纤维、BTX、液化和气化原料等高附加值产品。不同的研究者采用了不同的方法进行煤显微分选。本文综述了煤矿物的各种性质以及分离煤矿物的不同方法。

Coal macerals and their separation methodologies – A review

Macerals are microscopically recognizable organic entities found in coal. On the basis of their optical properties they are classified into three categories, liptinite, vitrinite, and inertinite. Reactive macerals, Vitrinite and liptinite, are responsible for the thermoplastic nature of coal during coke formation. It is also found that these macerals can be used for making some high valued products such as carbon fiber, BTX, liquefaction and gasification feedstock. There are various methods applied by different researchers for coal maceral separation method. This review aims to discuss the various properties of coal macerals and the different methodologies adopted for their separation.

期刊介绍： Metallurgical Research and Technology (MRT) is a peer-reviewed bi-monthly journal publishing original high-quality research papers in areas ranging from process metallurgy to metal product properties and applications of ferrous and non-ferrous metals and alloys, including light-metals. It covers also the materials involved in the metal processing as ores, refractories and slags. The journal is listed in the citation index Web of Science and has an Impact Factor. It is highly concerned by the technological innovation as a support of the metallurgical industry at a time when it has to tackle severe challenges like energy, raw materials, sustainability, environment... Strengthening and enhancing the dialogue between science and industry is at the heart of the scope of MRT. This is why it welcomes manuscripts focusing on industrial practice, as well as basic metallurgical knowledge or review articles.
