Step 1: Carbonization. Firstly, fire the raw materials in a rotary kiln. During the oneweek combustion process, the temperature needs to be maintained at approximately 840950 °F (450510 °C). After the end of combustion, close the air inlet, and after one to two hours of exhaust, close the exhaust hole.

Coal carbonization is the process by which coal is heated and volatile products (liquid and gaseous) are driven off, leaving a solid residue called coke. Carbonization of coal involves heating coal to high temperatures either in the absence of oxygen (O2) or in control quantity of O2. A gaseous byproduct referred to as coke oven gas (COG ...

Carbonization of coal is its decomposition by heat, out of contact with air, into a solid residue, coke, and liquid and gaseous distillation products. The main objective of the process of carbonization is the production of either hard coke or gas, the liquor being a valuable product in each case. If gas is the primary objective, coal with high ...

Coal production continues to grow globally due to the demand for low cost energy and iron and steel, as well as cement. Coal, based on the current extraction rates, will last about 115 years longer than conventional oil and gas reserves, with an estimated trillion tonnes of proven coal reserves worldwide. Ten countries are responsible for 90% of the total global coal production.

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.
