What are the products of destructive distillation of coal Class 8?
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.
Which is the main product of destructive distillation?
Coal tar is an important commercial product obtained by the destructive distillation of coal. It is a byproduct formed during the production of coke and coal gas from coal.
What is destructive distillation of coal and what are its by products?
When a substance is heated in the absence of air, the process is called destructive distillation. It results in the decomposition of the substance, bearing carbon rich residue. Destructive distillation of coal produces coke, coal tar, coal gas and ammonia solution.
What are the two products of coal?
The following products are obtained during coal processing:
- Coal tar – Used for building roads, in the manufacture of synthetic drugs, explosives, perfumes, paints, plastics, etc.
- Coke – Used to manufacture steel and in the extraction of metals.
- Coal gas – Used as a fuel in industries.
What is destructive distillation in coal?
destructive distillation. noun. the decomposition of a complex substance, such as wood or coal, by heating it in the absence of air and collecting the volatile products.
How is destructive distillation of coal carried out what are the main products obtained and their main uses?
Answer: Destructive distillation of coal is carried out by heating coal strongly to 1000 °C in the absence of air. It yields various useful organic and inorganic products. Coal tar: used to make pesticides, explosives, perfumes, etc. Ammonium compounds: making nitrogenous fertilizers.
What is destructive distillation of coal?
The 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 sulphur. When coal is heated in the absence of air, a number of products are obtained.
What does destructive distillation of coal Name the three products of destructive distillation of coal mean?
Answer: Coke, coal gas, gas carbon, coal tar,ammonia liquor, and “coal oil” are examples of commercial products historically produced by the destructive distillation of coal.
What are the three products of coal?

Which of these is obtained by destructive distillation of coal LPG coal gas CNG methane?
(d) methane. In destructive distillation of coal, coal is heated at high temperature in the absence of air to produce coal tar, coal gas, coke and liquor ammonia as its main by-products.
What are the substances produced by destructive distillation of coal mention any two uses of coal tar and coke?
Coke: Coke is a high-carbon product obtained by the destructive distillation of coal. Coke is used to manufacture steel and many other materials. Coal tar: It is obtained as a by-product in the process of making coke.
