What are the products of coal and petroleum?
О Fossil fuels are exhaustible resources. О Coke, coal tar and coal gas are the products of coal. О Petroleum gas, petrol, diesel, kerosene, paraffin wax, lubricating oil are obtained by refining petroleum.
What are the products formed by coal?
Coal And Its By – Products: Coke, Tar And Coal Gas. Coal is one of the most useful fossil fuels.
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.
What are the 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.
Is coal still being formed?
Coal is very old. The formation of coal spans the geologic ages and is still being formed today, just very slowly. Below, a coal slab shows the footprints of a dinosaur (the footprints where made during the peat stage but were preserved during the coalification process).
What is the main use of coal and petroleum?
Coal is used in homes and industries as a fuel. It is also used to generate electricity in power plants. Petroleum products (such as petrol and diesel) are used as fuels in vehicles. Other products (like kerosene and LPG) are used as domestic fuels for cooking.
How is petroleum better than coal as a fuel?
Coal is cheap and abundant, but it releases a lot of pollutants when burned. Petroleum, or crude oil, is harder to find and is typically a bit cleaner-burning — and, unlike coal, it can be pumped through pipelines and easily refined into fuels like gasoline or kerosene.
What is difference between coke and coal?
Coal is a lustrous, black fossil fuel that includes impurities, generates smoke, and generates less heat than coke when burned. Coke is a dingy, black coal waste that burns hotter and cleaner. … Coke is a fuel made from mineral coal that has been calcined or dry distilled.
How is coke obtained from coal?
Coke is obtained by destructive distillation of charcoal or coal in the furnace Destructive distillation is the chemical process involving the decomposition of coal or charcoal by heating to a high temperature in the absence of air or in the presence of limited amounts of oxygen.
How is coal tar formed 8?
It is a tough and porous black solid substance. It is prepared by heating coal in the absence of air. 1)When coal is heated in the absence of air,then coal gas and coal tar are eliminated,and coke is left behind as a black residue.
