Production Process: Coke is produced by heating coal in the absence of air, allowing it to transform into a nearly pure carbon form. Charcoal, on the other hand, is created by heating wood or organic matter in a controlled environment, removing volatile components through pyrolysis.

gasifier. (Show more) coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.

Coal spontaneous combustion is an incubation process where various factors can accelerate or decelerate the selfheating rate. Variations in coal selfheating from low ambient temperatures using an improved adiabatic oven testing procedure are presented. The new incubation test characterises the effects of moisture, seam gas and reactive pyrite ...

Solution. If coal is heated in the presence of air, then coal burns to produce mainly carbon dioxide gas and no other useful products were obtained. Other products obtained are water, heat and light. It is a gaseous fuel which is obtained by the strong heating of coal in the absence of air during the processing of coal to get the coke. Uses ...

The correct option is A heated in absence of air. Heating helps in separating the different materials which form the byproducts of coal. The absence of air prevents oxidation and any chemical reaction of coal with it. Therefore, coal should be heated in the absence of air in order to obtain the byproducts. This process is called destructive ...

Coking. Coking is the heating of coal in the absence of oxygen to a temperature above 600 °C to drive off the volatile components of the raw coal, leaving a hard, strong, porous material of high carbon content called coke. Coke consists almost entirely of hydrocarbons. The porosity gives it a high surface area, which makes it burn faster (as ...
