Destructive distillation of coal is a process where coal is heated in the absence of air, causing it to decompose into various volatile compounds and solid residues. This process yields by-products such as coal gas, coal tar, and coke. The volatile substances can be further processed into fuels and chemicals, while coke is primarily used as a fuel and reducing agent in Metallurgy. Overall, it is a method for extracting valuable materials from coal while minimizing combustion.

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.
What is coke in chemistry?
In chemistry, "coke" refers to a porous, carbon-rich material that is produced when coal is heated in the absence of air. It is primarily composed of carbon with small amounts of ash and sulfur. Coke is commonly used as a fuel and as a reducing agent in various industrial processes, such as in the production of steel.
What is the difference between bitumen and crude oil?
'asphalt' refers to a mixture of mineral aggregate and bitumen (bitumen)is the black liquid which is extracted from the crude oil....
What is the difference between coal coke coal tar and coal gas?
COAL: A combustible black or dark brown rock consisting chiefly of carbonized plant matter, found mainly in underground seams and used as fuel. Coal is composed primarily of carbon along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen COKE: A solid fuel made by heating coal in the absence of air so that the volatile components are driven offCOAL TAR: Coal tar is a brown or black liquid of extremely high viscosity. Coal tar is among the by-products when coal is carbonized to make coke or gasified to make coal gas.COAL GAS: A mixture of gases (chiefly hydrogen, methane, and carbon monoxide) obtained by the destructive distillation of coal
Where are aromatic compounds usually found?
The aromatic compounds or benzene is mostly found in plant and tree oils. The compound is gathered by coal distillation.
What is destructive distillation of coal?
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.
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 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 charcoal and wood charcoal are formed respectively. Gas carbon is also released and tar is made.
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?
coke mean Carbon is in it's natural state... C
