Coal utilization Coal utilization Carbonization (coke making): Coke is the solid carbonaceous residue that remains after certain types of coal are heated to a high temperature out of contact with air. The process of heating coal in this manner is referred to as carbonization or coke making. Hightemperature carbonization, with which this section is concerned, is practiced to produce a coke
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.
Carbonization is a pyrolytic reaction, therefore, is considered a complex process in which many reactions take place concurrently such as dehydrogenation, condensation, hydrogen transfer and isomerization.. Carbonization differs from coalification in that it occurs much faster, due to its reaction rate being faster by many orders of magnitude.
Carbonisation is the term used to denote the heating of coal in the absence of air. In these circumstances, volatile matter (VM) is removed. The volatiles are higher in hydrogen content than the basic coal, which therefore increases in carbon hence, carbonization.
Coal is something that we might have come across at least once in our lifetime. It is a common substance used in many homes and even in big industries. That being said, we will be studying about coal and some of its uses here. Coal is basically a combustible sedimentary rock usually occurring in parts known as coal beds or coal seams.
Other articles where Carbonization is discussed: chemical industry: Benzene: it was obtained from the carbonization (heating) of coal, which produces coke, combustible gas, and a number of byproducts, including benzene. Carbonization of coal to produce illuminating gas dates back in England to the very early years of the 19th century. The process is still employed in some countries, but

So this technology no longer using the coal, carbon source as for preheating source. Before the start of the carbonization we choose simple biomass gasifier equipment separately providing combustible gas as heat source for the carbonization process. Carbonization Machine Was Installed In Malaysia
Therefore, this study examined the coke and energy recovery potential of a newly discovered lignite coal from Ogboligbo (OGB) in Kogi state of Nigeria through carbonization of OGB coal in a muffle
Coal is a black sedimentary rock. It usually occurs in coal beds found in coal mines. Coal comprises of carbon, hydrogen, oxygen, sulphur, etc. When dead plants and animals decay and convert into peat which in turn is converted into lignite, then subbituminous coal, after that bituminous coal, and lastly anthracite. Hence, coal is a fossil fuel.

Coal Carbonization for Coke Production. 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.
Carbonization of coal can be carried out at the following three temperature ranges. Low temperature carbonization is normally carried out in the temperature range of 500 deg C to 700 deg C. In this type of carbonization, the yields of liquid products are higher and there is lower gaseous product yield.
Collectively, carbonization of coal produces four organicdominated byproducts: coke (thermally stable coal minerals bound by graphitic carbon), coal tar (liquid pyrolytic condensate), soot (solid pyrolytic condensate), and hydrocarbon gases (methane, ethane, acetylene, carbon monoxide, and others).
Carbonization of coal, thermal decomposition of coals in the absence of air, represents one of the largest utilizations of coal, and is an essential process for production of a carbonaceous residue (coke), gas, and tar. The first attempts to coke bituminous coal
