WEBThe process of heating coal in the absence of air is called the destructive distillation of coal. Coal contains a number of elements such as carbon, hydrogen, oxygen, nitrogen, and sulfur. The tube is kept horizontally and another tube (water containing ) is fixed vertically.
WEBCoke is a solid carbonaceous material derived from destructive distillation of lowash, lowsulphur bituminous coal . The volatile constituents of the coal—including water, coalgas, and coaltar —are driven off by baking in an airless oven at temperatures as high as 2,000 degrees Celsius. This fuses together the fixed carbon and residual ash.
WEBAnother 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. Wood, for example, when treated in this way yields acetic acid, methyl or wood alcohol, charcoal, and a number of hydrocarbons.

WEBDistillation separates two or more liquid components in a mixture using the principle of relative volatility or boiling points. The greater the difference in relative volatility the greater the nonlinearity, and the easier it is to separate the mixture using distillation. The process involves the production of vapor by boiling the liquid ...
WEBSep 4, 2020 · The two important products obtained from the destructive distillation of coal are: Coal gas and coal tar. The residue left in this process is coke. Coke is used mainly as a reducing agent in the extraction of metals. Question 8. Where do we get coal and how is it formed? Answer: We get coal deep in the earth's crust in coal mines.
WEBAug 2, 2022 · The process of heating complex organic substances in the absence of air so that they break down into a mixture of volatile products, which are condensed and collected. At one time the destructive distillation of coal (to give coke, coal tar, and coal gas) was the principal source of industrial organic chemicals.
WEBCoke is a grey, hard, and porous coalbased 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 an important industrial product, used mainly in iron ore smelting, but also as a fuel in stoves and forges when air pollution is a concern.

Coke Production: Destructive distillation of coal is crucial for coke production. Coke, the solid residue, serves as a vital reducing agent and heat source in metallurgical processes ...
WEBThe process of heating coal in the absence of air is known as the destructive distillation of coal. Coke, coal tar and coal gas are the byproducts obtained during the destructive distillation of coal. Suggest Corrections.
WEB4 days ago · What is a Coal Gas? Coal gas is a gaseous mixture, mainly composed of methane, hydrogen, and carbon monoxide that are formed by the destructive distillation (it means heating in the absence of air) of bituminous coal and is also used as a fuel. At times, coal steam is added to react with the hot coke, therefore increasing the yield of gas.
WEB(1)Destructive distillation is a chemical process of heating substances in the absence of air or in limited supply of air.
