Test Series. Coal is a fossil fuel formed from the remains of plants that lived and died millions of years ago. It has been an energy source for centuries and has various associated products. Coal Products generate heat, industrial power generators, make cast iron, and more. Coke, tar, and coal gas are all byproducts of coal processing.
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 ...

Examples of these resources are forests, wildlife, minerals, coal, petroleum, natural gas, etc. Here, we will learn about some exhaustible natural resources like coal, petroleum, and natural gas.
Britain In 1589, a patent was granted to Thomas Proctor and William Peterson for making iron and steel and melting lead with "earthcoal, seacoal, turf, and peat". The patent contains a distinct allusion to the preparation of coal by "cooking".
(b) The various products obtained by destructive distillation of coal are: coal gas, coal tar and coke. 1. Coal Gas: Coal gas 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 coke. Coal gas is mainly a mixture of methane and hydrogen, with some carbon monoxide.
