Destructive distillation of coal is heating coal in a retort until its chemical structure breaks down (destructive or nonreversible). The products are: coal gas, coal tar, and coke.
Ordinary distillation is reversible by just remixing the products. Destructive distillation is nonreversible.
Destructive distillation of coal is a process in which coal is heated in the absence of air to break it down into various components, such as gas, liquid, and solid products. This process is used to produce substances like coal gas, coal tar, and coke, which have industrial and commercial applications.

Which substances is obtained by heating coal in absence of air?
When coal is heated in the absence of air, it undergoes a process called destructive distillation or pyrolysis, resulting in the formation of substances such as coal gas, coal tar, and coke.
How is it produced coke from coal?
Coke is produced from coal through a process called destructive distillation. In this process, coal is heated in the absence of air to drive off volatile components, leaving behind coke. The coke produced is a porous material that is used as a fuel and as a reducing agent in the smelting of iron ore.
What is carbonisation of coal?
Carbonization of coal is a process where coal is heated in the absence of air to drive off volatile compounds, leaving behind a residue of carbon. This process results in the formation of coke, a high-carbon and low-impurity fuel used in industrial processes like steelmaking.
What is formed from the destructive distillation of animal bones or wood?
Bone char is formed from the destructive distillation of animal bones, while wood tar and wood gas are formed from the destructive distillation of wood.
How coal tar is formed?
Coal tar is formed during the process of coal gasification or coking, where coal is heated in the absence of air to produce coal gas and other byproducts. The tar is a dark, thick liquid that contains various hydrocarbons and is collected as a byproduct of these processes.
Which substances is obtained by heating coal in absence of air?
When coal is heated in the absence of air, it undergoes a process called destructive distillation or pyrolysis, resulting in the formation of substances such as coal gas, coal tar, and coke.
What is coke in chemistry?
In chemistry, "coke" refers to a carbonaceous solid produced by the destructive distillation of coal or petroleum. It is primarily used as a fuel or as a reducing agent in the production of metals.
How is it produced coke from coal?
Coke is produced from coal through a process called destructive distillation. In this process, coal is heated in the absence of air to drive off volatile components, leaving behind coke. The coke produced is a porous material that is used as a fuel and as a reducing agent in the smelting of iron ore.
What is tar?
Tar is a dark, oily, viscid mixture of hydrocarbons obtained by destructive distillation of resinous wood, coal, or ect. It's also what most roads are paved with.
What is carbonisation of coal?
Carbonization of coal is a process where coal is heated in the absence of air to drive off volatile compounds, leaving behind a residue of carbon. This process results in the formation of coke, a high-carbon and low-impurity fuel used in industrial processes like steelmaking.
What is coking process?
§Destructive distillation of coal to make cokea process for thermally converting the heavy residual bottoms of crude oil entirely to lower-boiling petroleumproducts and by-product petroleum coke.
What is formed from the destructive distillation of animal bones or wood?
Bone char is formed from the destructive distillation of animal bones, while wood tar and wood gas are formed from the destructive distillation of wood.
Why is bitumen obtained from fractional distillation preferred over destructive distillation?
Bitumen obtained from fractional distillation is preferred over destructive distillation because it yields a higher quality product with more consistent properties. Fractional distillation separates bitumen based on boiling points, resulting in a cleaner and more refined product compared to the more varied and impure composition obtained from destructive distillation. Additionally, fractional distillation is a more controlled and efficient process, allowing for better quality control and reproducibility.
How coal tar is formed?
Coal tar is formed during the process of coal gasification or coking, where coal is heated in the absence of air to produce coal gas and other byproducts. The tar is a dark, thick liquid that contains various hydrocarbons and is collected as a byproduct of these processes.
What are the social and economic benefits of fractional distillation of coal?
Fractional distillation increases the value of coal and thus makes it a good business venture. The by product of this type of coal can be used in roofing, waterproofing, and paving.
Chemical formula of coke?
The chemical formula of coke is carbon, typically expressed as C. It is a form of carbon that is derived from the destructive distillation of coal.
What is fractional distillation of coal?
Fractional distillation of coal is a process in which coal is heated to produce a range of hydrocarbon products, such as gases, liquids, and solids. These products can be further refined and used as fuels or chemical feedstocks. The process takes advantage of the different boiling points of the components in coal to separate them based on their molecular weight and properties.
