Kinetic Analysis of Dehydration of a Bituminous .

The current investigation focuses on the kinetics of water liberation during a drying process of a bituminous coal. Using the technique of thermogravimetric analysis (TGA), the mass change of a sample was recorded over the temperature range from 35 to 115 °C at a heating rate of 0.1, 0.2, 0.4, or 0.8 °C/min. The measurements were then analyzed by applying the Coats–Redfern .

Coal - Wikipedia

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams.Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is 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.
