This chapter discusses coal carbonization. Coal carbonization involves the destructive distillation of coal, and during this process, as much as 50% of the weight of the coal feedstock is driven off as gaseous and volatile components. These are regarded as byproducts of the coking process, and include combustible gases (for example, methane ...

Coal gas, also known as a gaseous mixture, is a fuel made up of hydrogen, methane, and carbon monoxide produced by destructive distillation (continuous heating in the absence of air) of bituminous coal. Coal is mostly made up of carbon, with varying proportions of additional elements such as hydrogen, sulphur, oxygen, and nitrogen.

Destructive Distillation. The term destructive distillation generally refers to the processing of organic material without air or in the presence of a minimal amount of oxygen and other reagents, catalysts, or solvents, such as steam or phenols by heating it to a high temperature. It works on the principle of pyrolysis and large molecules are "cracked" during the process.

Figure 5 Destructive Distillation. It is a process in which coal is heated at very high temperature in the absence of air to obtain various useful products from it. Consider the diagram below to understand the process of destructive distillation. Different products obtained through this process are coal gas, coal tar, coke and liquor ammonia.

Destructive Distillation is defined as a chemical reaction by which unprocessed material is subjected to decomposition by heating, thereby producing 'cracks' in relatively large molecules. It is used for the treatment of certain organic substances with limited amounts of oxygen and certain reagents, solvents, or catalysts such as phenols and steam.

Destructive distillation is the process of decomposing a material by heating in a closed container in an inert atmosphere and collecting off the volatile constituents. Destructive distillation of coal produces many byproducts. In the process, heated coal turns into coke, ammonia dissolves in water to form ammonia liquor and coal gas and coal ...

Destructive distillation of coal involves heating coal to high temperatures (about (1000,^circ {rm{C}})) in the absence of air. The process causes its decomposition into different products solid and gaseous. Some of the gases condense while some dissolve in water. Some of the products obtained in the process are coke, coal, coal tar, and ...

gasifier. (Show more) coal gasification, any process of converting coal into gas for use in illuminating and heating. The first illuminating gas was manufactured from coal in England in the late 18th century by the process of carbonization or destructive distillation, heating coal in the absence of air, leaving a residue of coke as a byproduct.
