The coking of coal J. W. Patrick Various aspects of the constitution of coal, in so far as they relate to the coking process, are described and it follows from this that the coking process can be subdivided into several distinct stages, the most important of which is considered to be that involving the development of plasticity.

Coal is a combustible black or brownishblack sedimentary rock, formed as rock strata called coal is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is a type of fossil fuel, formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
