What are the differences between charcoal, coal and coke

What are the differences between charcoal, coal and coke? Charcoal is a fuel that comes from the incomplete burning of wood. The difference between wood and charcoal is that it has a higher carbon content, about 98%, and is therefore more efficient. It was used massively during the Middle Ages to forge iron for the elaboration of swords, armor

Aug 31, 2009Coking coal is non-coking coal that has been heated in the absence of oxygen to drive off volatiles. Coal mines must be well ventilated and safeguarded from explosions because broken up coal can give off volatile vapors. Bituminous coal should give off more vapor than harder anthracite coal.

What is the difference between Coke and charcoal?

Coking coal is converted to coke by driving off impurities to leave almost pure carbon. The physical properties of coking coal cause the coal to soften, liquefy and then resolidify into hard but porous lumps when heated in the absence of air. This process results in a hard porous material - coke.

Influence of coal fluidity on coal blend and coke quality

Jul 18, 2013An empirical relation has been developed between actual blend fluidity and calculated fluidity using logarithmic weighted average from fluidity of individual coals. Blending of non-coking coals above 20% with the hard coking coals used in this research decreases the blend fluidity and impairs the coke quality.

Oct 08, 2014The most important quality for a good coking coal is the index of caking/plasticity which is the ability, when heated in a non-oxygen atmosphere to become plastic and give off the volatiles and then reform as a solid. Heating coals are pretty common and account for the vast majority of coal reserves. Good coking coal is much less common.

Differentiation of coking non-coking coals: From physical appearance it is very difficult if not impossible to differentiate between non-coking a coking coal. A non – caking coal is that coal which when heated in the absence of air for e.g. as in the determination of VM, leaves a powdery residue. A non-caking coal is always a non-coking coal.
