During gasification, the coal is mixed with oxygen and steam while also being heated and pressurized. During the reaction, oxygen and water molecules oxidize the coal into carbon monoxide (CO), while also releasing hydrogen gas (H 2). This process has been conducted in both underground coal mines and in the production of town gas. C (as Coal ...

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.
