Coal Gas

Coal is mostly made up of carbon, with varying proportions of additional elements such as hydrogen, sulphur, oxygen, and nitrogen. Coal is generated when dead plant matter decays into peat, which is then transformed to coal over millions of years by the heat and pressure of deep burial. Typical composition of the Coal gas is as follows ...
