The byproduct obtained after processing coal is coke.
Which by product is obtained after processing coal?
1 Answer. Coal when processed in industry gives coke, coal tar and coal gas. Coke is used in the manufacture of steel and in extraction of many metals. Coal tar is used as starting material for manufacturing various substances such as synthetic dyes, drugs, explosives, perfumes, paints, etc.18 мая 2018 г.
Which products are obtained from coal?
COKE, COAL TAR, COAL GAS are the products obtained from coal.
- Coal Gas is used as a fuel for cooking food.
- Coke is used as a fuel and as a reducing agent in steel manufacturing .
- Coal Tar is used to make plastics, paints, dyes, naphthalene balls and explosives.
Is coal obtained from petroleum?
Petroleum, also called crude oil, is a fossil fuel. Like coal and natural gas, petroleum was formed from the remains of ancient marine organisms, such as plants, algae, and bacteria. … Coal, natural gas, and petroleum are all fossil fuels that formed under similar conditions.
Which products are formed when coal and petroleum are burned?
Products formed during combustion of fossil fuels.
The primary pollutants are Carbon Monoxide (CO), Carbon Dioxide (CO2), Sulfur (SO2), Nitrogen Dioxide (NOx), Nitric Oxide (N2O), Volatile organic compounds (VOCs), and Hydrocarbons (HCs).
Is coke obtained from coal tar?
Coal tar: It is obtained as a by-product in the process of making coke. Though its colour is the same as coke, tar is a highly viscous liquid.
Which gas is produced when coal is burnt in air?
Why is coal still used?
That’s largely because of the shale gas revolution, which suddenly made natural gas cheaper than coal for generating electricity. … Global coal use continues to rise, especially in developing economies. About 38 percent of global electricity comes from coal, and in many countries it’s a mainstay for industrial uses, too.
How is coal gas obtained where is it used?
Coal gas, gaseous mixture—mainly hydrogen, methane, and carbon monoxide—formed by the destructive distillation (i.e., heating in the absence of air) of bituminous coal and used as a fuel. … Coal tar and coke (qq. v.) are obtained as by-products.
What is Coke and its uses?
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 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.
What are 4 types of coal?
Coal is classified into four main types, or ranks: anthracite, bituminous, subbituminous, and lignite. The ranking depends on the types and amounts of carbon the coal contains and on the amount of heat energy the coal can produce.
Which is the cleanest fuel?
What is the origin of coal and petroleum?
Coal and petroleum are formed as a result of degradation of ancient plant life which lived millions of years ago. These dead plant matter started to pile up, eventually forming a substance called peat. Over time, heat and pressure from geological processes transformed these materials into coal.
Why Coke is not used as fuel?
The term means a product similar to coal and mined the same way. Coal is cheaper and that is why it is used more often. … Coke is cleaner and other methods should be looked into before coal and oil run out.
What is difference between coal and petroleum?
Basically, these differences center around the fact that coal is found at its site of deposition as a solid and relatively pure massive organic substance, whereas petroleum is liquid and migrates readily from its place of origin into porous reservoir rocks.
Which is the least polluting fuel for vehicles?
Compressed Natural Gas (CNG)
