Coalification is a geological process of formation of materials with increasing content of the element carbon from organic materials that occurs in a first, biological stage into peats, followed by a gradual transformation into coal by action of moderate temperature (about 500 K) and high pressure in a geochemical stage.
Coal is a black or brownishblack sedimentary rock that can be burned for fuel and used to generate electricity. It is composed mostly of carbon and hydrocarbons, which contain energy that can be released through combustion (burning). Coal is the largest source of energy for generating electricity in the world, and the most abundant fossil fuel ...

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".
Plasmochemical hydrogenation of coal is a new process of direct production of acetylene and alkenes in the gaseous phase, in contrast to traditional processes of coal hydrogenation (liquefaction). Propanebutane mixture (50% C 3 H 8 +50% C 4 H 10), 200 t −1, is used as a hydrogenating agent instead of hydrogen, 2000 t −1.
