Coal Liquefaction The Canadian Encyclopedia

Coal liquefaction is a process that converts coal from a solid state into liquid fuels, usually to provide substitutes for petroleum products. Coal liquefaction processes were first developed in the early part of the 20th century but later application was hindered by the relatively low price and wide availability of crude oil and natural gas.

Blank roasting and bioleaching of stone coal for vanadium

Zhao et al. (2017) found that in the process of roasting stone coal, vanadium-bearing muscovite with quartz was transformed into feldspar, in which the Al (V)-O bond in muscovite was destroied. For vanadium recycling from stone coal for the first time, our research team proposes a combination of blank roasting without additives and bioleaching using silicate bacteria that underwent compound ...
