The various useful products obtained by processing the coal by heating in the absence of air are: (1) Coal gas. (2) Coal tar. (3) Coke. The strong heating of coal in the absence of air is called destructive distillation of coal. If coal is heated in the presence of air, then coal burns to produce mainly carbon dioxide gas and no other useful ...

Fractional distillation is a type of distillation which involves the separation of miscible liquids. The process involves repeated distillations and condensations and the mixture is usually separated into component parts. The separation happens when the mixture is heated at a certain temperature where fractions of the mixture start to vaporize.

The products which are obtained by the process of destructive distillation are coke, coal tar and coal gas. Coke: It is a solid black substance. It is nearly a pure form of carbon. It is used in the fabrication of steel. Also in the extraction of metals, it is used as a reducing agent. Commonly, it is used as a fuel.

A process by which organic substances such as wood, coal, and oil shale are broken down by heat in the absence of air. This causes them to break down into solids, liquids, and gases, which are then used to make products such as coke, charcoal, oils, and ammonia. "Destructive distillation." HOPE IT HELPS YOU .

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.

Manufacturing process. Coal tar is obtained by cooling the gas that is formed during the destructive distillation of coal to approximately ambient temperature. It is a black, viscous liquid composed primarily of a complex mixture of condensedring aromatic hydrocarbons. It may contain phenolic compounds, aromatic nitrogen bases and their alkyl ...

Destructive distillation is a chemical process of the decomposition of unprocessed material by heating it to a high temperature. It is the processing of organic material in the absence of air or in the presence of limited amounts of oxygen. It is an application of pyrolysis. This process breaks up or 'cracks' large molecules.
