Question: Which products are formed in industries by processing of coal?

What are the products of processing of coal?

Coal is processed in industry to get some useful products such as coke, coal tar and coal gas. It is a tough, porous and black substance. It is an almost pure form of carbon. Coke is used in the manufacture of steel and in the extraction of many metals.

What are the 3 useful products of coal?

The three useful products of coal are following:

  • Coke: It is a tough, porous and black substance. It is almost pure form of carbon.
  • Coal tar: It is a mixture of about 200 substances. It is a black, thick liquid with unpleasant smell.
  • Coal gas: It is obtained during the processing of coal to get coke.

Which gas is produced when coal is burnt in absence of air?

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. Sometimes steam is added to react with the hot coke, thus increasing the yield of gas.

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.

How is coke obtained?

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.

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.

What is coal an example of *?

Coal is an example of Sedimentary rocks. Coal is a biochemical sedimentary rock because coal is formed from organic matter or sediment that comes from biological processes. Coal is typically found near swampy areas, or areas where sediment has little contact with oxygen.
