The process of destructive distillation can be viewed as an application of the concept of pyrolysis (the thermal decomposition of certain substances at very high temperatures under relatively inert atmospheres). The process of destructive distillation is known to .
Destructive distillation of a tonne of coal can produce 700 kg of coke, 100 liters of liquor ammonia, 50 liters of coal tar and 400 m 3 of coal gas. Destructive distillation is an increasingly promising .
Jan 12, 2019· Destructive distillation. When any substance is heated in the absence of air and forms a number of products, the process is known as destructive distillation of coal. As we know that c oal contains a number of elements such as carbon, hydrogen, oxygen, nitrogen and sulphur. The products which are obtained by the process of destructive ...
Coke is a grey, hard, and porous fuel with a high carbon content and few impurities, made by heating coal or oil in the absence of air—a destructive distillation process. It is .
Dec 26, 2018· The process of distillation gives a variety of valuable chemical products. The residue of distillation is coal tar pitch, which is further processed into coal tar pitch of desired chemical and physical properties. The primary objective of coal tar distillation process .
Another form of distillation involves heating out of free contact with air such substances as wood, coal, and oil shale and collecting separately the portions driven off; this is known as destructive distillation.

Destructive distillation. 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 .
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 also used to derive coal tar using a similar process. A number of useful volatiles can be distilled from bituminous coal, including pyrene and other polycyclic aromatic was also historically distilled into coal .
Process Description1,2 All metallurgical coke is produced using the "byproduct" method. Destructive distillation ("coking") of coal occurs in coke ovens without contact with air. Most U. S. .
Walter Vergara, David Pimentel, in Advances in Energy Systems and Technology, Volume 1, 1978. 2 Pyrolysis. Pyrolysis or destructive distillation is an irreversible chemical change caused by the action of heat in the absence of oxygen (in the presence of oxygen the name of the process is combustion). Without oxygen the energy input splits the chemical bonds and leaves the energy stored.
In laboratory, the destructive distillation of coal is carried out as follows: Two hard glass boiling tubes are taken. A small quantity of powdered coal is placed in one of the boiling tubes (tube A).About 20 ml of water is taken in tube B. The apparatus is set as shown. Coal powder is .
Coal tar: It is obtained as a byproduct in the process of making coke. Though its colour is the same as coke, tar is a highly viscous liquid. It also has an extremely unpleasant smell. Uses: Coal .
Coal is formed when the organic matter (mainly big plants and trees) trapped deep inside the earth decomposes under the influence of heat and pressure. It can be converted to coke by destructive distillation. This process of distillation .
Destructive distillation is the chemical process of the decomposition of unprocessed material by heating it to a high temperature; the term generally applies to processing of organic material in the .
