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.

It can be seen from Figure 3 that under the same pressure condition, with the increase in temperature, the gas adsorption capacity of coking coal shows a downward trend. This is because the adsorption of coal to gas belongs to physical adsorption, and adsorption is an exothermic process (Wang et al., 2012).So, with the rise in temperature, the gas molecules move more violently, and the time ...
