Coal and Petroleum Test

Directions For Questions

Gaseous fuel have become very popular these days. The following are the advantages of gaseous fuels.

They have high calorific value.
They do not produce smoke and leave no ash after combustion
Gaseous fuels can flow through pipes and can be ignited at a moment's notice at any place. No special devices are required for their combustion
Coal gas is a good gaseous fuel as it contains 95% combustible gaseous such as hydrogen, methane, carbon monoxide, etc. It is obtained by destructive distillation of coal at about $$1000^oC$$.
Water gas which is essentially a mixture of hydrogen and carbon monoxide is prepared by passing steam over incandescent coke. The reaction is however endothermic.
Producer gas which possesses lowest calorific value is prepared by passing air over red hot coke. It contains mainly nitrogen and carbon monoxide.
Semiwater gas is a mixture of water gas and producer gas.
Oil gas which is used in laboratories is obtained by cracking of kerosene. It is a mixture of hydrocarbons (saturated and saturated ) mainly lower hydrocabon. $$LPG$$ (liquefied petroleum gas), which contains $$C_3$$ and $$C_4$$ hydrocarbons of the alkane and alkane series supplied in cylinders for domestic uses is very popular these days.
