What are the products 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..
What is the highest grade of coal?
AnthraciteAnthracite: The highest rank of coal. It is a hard, brittle, and black lustrous coal, often referred to as hard coal, containing a high percentage of fixed carbon and a low percentage of volatile matter.
Why coal is heated in the absence of air?
Coal And Petroleum Name this process. Write the name of the two products obtained during this process. When coal is heated in the absence of air, it breaks up and provides a large number of organic compounds and some inorganic compounds. … In this process coal tar and coal gas can obtained.
What is coal tar made of?
Coal tar is a thick dark liquid which is a by-product of the production of coke and coal gas from coal. It has both medical and industrial uses. Medicinally it is a topical medication applied to skin to treat psoriasis and seborrheic dermatitis (dandruff).
How do you extract coal?
Coal can be extracted from the earth either by surface mining or underground mining. Once coal has been extracted, it can be used directly (for heating and industrial processes) or to fuel power plants for electricity. If coal is less than 61 meters (200 feet) underground, it can be extracted through surface mining.
How do we obtain coke from coal?
Metallurgical coke is produced by destructive distillation of coal in coke ovens. Prepared coal is “coked”, or heated in an oxygen-free atmosphere until all volatile components in the coal evaporate. The material remaining is called coke.
How is coke obtained from coal state three important uses of coke?
Coke is formed by the destructive distillation of coal. … 1) Coke is used as a domestic fuel. 2) Coke is used as a reducing agent in metallurgical processes. 3) Coke is used for producing fuel gases.
What is Coke vs coal?
By distilling bituminous coal in retorts to obtain gas for illumination, or by burning it in kilns or pits, the residue left behind is called coke, which is simply coal charcoal, and is nearly pure carbon.
How is coal formed?
Coal is mostly carbon with variable amounts of other elements; chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.
Can we make steel without coal?
Well, yes, we can. At present, the ultimate solution is considered to be ‘green’ steel, made with renewable hydrogen. … You see, carbon (in the form of carbon monoxide) is currently the dominant method of converting iron ore into iron.
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.
Does Coke burn hotter than coal?
Coal is a shiny, black fossil fuel that contains impurities, emits smoke when burned, and produces less heat than coke. Coke is a dull, black byproduct of coal that burns hotter and cleaner. … However, blacksmiths still rely on coke as an efficient source of fuel for the forge.
