heating of coal in absence of air
by heating the absence of air
coal carbonisation is the enrichment of coal properties. it is done by heating under absence of air

Charcoal is usually produced by slow pyrolysis, the heating of wood, sugar, bone char, or other substances in the absence of oxygen (see pyrolysis, char and biochar). The resulting soft, brittle, lightweight, black, porous material resembles coal and is 50% to 95% carbon with the remainder consisting of volatile chemicals and ash.[1]tile constituents from animal and vegetation substances.

Coal can be composed of a number of different things, primarily carbon. Because "Coal" does not refer to a single element or group of elements, there is no specific answer to this question.
Coke is made by heating coal in the absence of oxygen to about 2000 degrees Fahrenheit. Hard coking coal forms high-strength coke, while soft coking coal produces a lesser quality coke.
People still use coal because it satisfies lots of needs at an affordable rate. Coal is primarily used for heating purposes, but can also be used to make plastics, steel, coke (a hard, dry substance containing carbon that's produced by heating bituminous coal to a very high temperature in the absence of air), and electricity purposes.
coal tar
i am a solid substance left after heating coal or petol

no they dont, why because the substances in coal are more than diamonds if you compare them
