What advantage does coke have over coal as a fuel?
(i) Coke produces more heat than an equal mass of coal. (ii) It produces ni smoke on burning and leaves no residue and as such does not cause air pollution. (iii) It is used as a reducing agent in the extraction of metals from their ores.
What happens when coal tar is distilled Class 8?
Coal tar is obtained by cooling the gas that is formed during the destructive distillation of coal to approximately ambient temperature. … The part of coke-oven tar that is normally distillable at atmospheric pressure boils at up to ~400 °C and contains principally aromatic hydrocarbons.
