Effects of hydrogen donor additives on the coking properties of high-temperature coal extracts
Refcoal is a carbon precursor obtained by alkali-mediated extraction of coal with aprotic solvents such as DMF. Refcoal can be converted into a graphitic material through appropriate heat treatment. Graphitisable materials require the development of an intermediate liquid crystalline mesophase. Thus...
