Solution. Coal gas is obtained during the processing of coal to get a coke. It is used as a fuel in many industries situated near coal processing plants. Coal gas was used for street lighting for the first time in London in 1810 and in New York around 1820. Nowadays, it is used as a source of heat rather than light.

The total amount of tar obtained during the whole test was not too high and was approximately 3 dm 3 (approx. kg), while the volume of a single sample was dm 3. Considering that 9163 Nm 3 of process gas was obtained, the concentration of tar in the gas was g/Nm 3. This is a low value for the underground gasification process.
