The journal was known as Coal Preparation from 1984 to 2007, and the International Journal of Coal Preparation and Utilization from 2008 to the present. The current editor-in-chief is Barbara J. Arnold, a professor of practice in mining engineering from Pennsylvania State University .
Most coal is used as fuel. 27.6% of world energy was supplied by coal in 2017 and Asia used almost three-quarters of it. [79] Other large-scale applications also exist. The energy density of coal is roughly 24 megajoules per kilogram [ 80 ] (approximately 6.7 kilowatt-hours per kg).
The coal industry uses the term "clean coal" to describe technologies designed to enhance both the efficiency and the environmental acceptability of coal extraction, preparation and use, [43] but has provided no specific quantitative limits on any emissions, particularly carbon dioxide.

Coal liquefactions originally was developed at the beginning of the 20th century. [2] The best-known CTL process is Fischer–Tropsch synthesis (FT), named after the inventors Franz Fischer and Hans Tropsch from the Kaiser Wilhelm Institute in the 1920s. [3] The FT synthesis is the basis for indirect coal liquefaction (ICL) technology.
