Primary gaseous fuels Secondary gaseous fuels
Natural gas

  • Petroleum fields are the main sources of natural gas.
  • It mainly contains methane.
  • It is used for domestic purposes and in industry.
 (i) Cooking gas(LPG)

  • It is a mixture of butane and isobutane.
  • It is obtained from petroleum.

(ii) Producer gas

  • It is obtained from coke.
  • It is mixture of Co, H2 , N2, Co2 and CH4.

(iii) Coal gas

  • It is a mixture of CO, CO2, H2, N2, CH4, O2 and unsaturated hydrocarbons like C2 H4 , C2 H2 , G6 H6 etc.
  • It is obtained from coal.

(iv) Gobar gas

  • Its composition is CH4, CO2, H2 and H2S.
  • It contains 55% of methane , which is an excellent fuel.
  • It is obtained by an anaerobic fermentation of cattle dung.

(v) Biogas

  • It is produced by the degradation of biological matters and by the bacterial action in the absence of free oxygen.
  • Biogas can also be produced from sewage and other organic wastes.
