What are the products of fractional distillation of coal gas?

What are the products of coal gas?

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.

What are the product of distillation of coal?

Coke, coal gas, gaseous carbon, coal tar, ammonia liquor, and coal oil are examples of commercial products historically produced by the destructive distillation of coal.

Which useful products are obtained by the fractional distillation of coal?

Answer: Products obtained by destructive distillation of coal are coke and coal tar and the products obtained by the fractional distillation are petroleum gas.

What is fractional distillation of coal?

Fractional distillation of tar refers to the process by which components in a chemical mixture are separated by taking advantage of the difference in their boiling points. … The residue of distillation is coal tar pitch, which is further processed into coal tar pitch of desired chemical and physical properties.

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.

Coal And Its By – Products: Coke, Tar And Coal Gas.

Is coal tar used in extraction of metals?

Like charcoal, it Is a good fuel and burns without smoke. It is largely employed as a reducing agent in the extraction of metals from their ores. It is also used in making fuel gases like water gas and producer gas. (2) Coal tar (liquid): Coal tar is a mixture of different carbon compounds.

Which material is obtained when coal is strongly heated in the absence of air?

When coal is heated strongly in the absence of air, a large number of organic and some inorganic compounds are formed. This process is called destructive distillation of coal. Two products of this process are coal tar and coal gas.
