Coal Gas Preparation By destructive distillation of coal. Composition H,-45-55 % N2-2-12% CH4 = 25-35 % CO, = 0-3% = 4-11% ,-1-1,5 % Ethylene, acetylene, benzene, etc. = 3-5 % Uses It is used as illuminant, as fuel and to provide inert atmosphere in the metallurgical processes
Natural Gas It is found along with petroleum below the surface of earth Composition CH4-60-80 % Higher hydrocarbons 2-12% C2H6 = 5-10%,C3H8-3-18% Uses It is used as a fuel.Its partial combustion yields carbon black (reinforcing agent for rubber)
Oil Gas Preparation Heated in Kerosene Mixture of simple hydrocarbons absence of air Uses It is used as fuel in laboratories in Bunsen burners. Wood Gas Preparation Destructive distillation of wood gives wood gas (CH4, C2H H2 Uses It is used as fuel.
Liquified Petroleum Gas (LPG) Composition n-butaneIso-butane Uses It is used as domestic fuel. Important Information
