Analysis of syngas production and reaction zones in hydrogen

Underground coal gasification is an alternative gasification technique to exploit the chemical energy of the coal reserves in situ. Basically, the UCG is similar to surface coal gasification techniques in which coal, with the help of oxidizers, is dried, pyrolyzed, combusted and then gasified in reducing environment in order to produce synthesis gas that contains combustible gases such as CO

The technical feasibility of underground coal gasification (UCG) has been established through many field trials and laboratory-scale experiments over the past decades. However, the UCG is site specific and the commercialization of UCG is being hindered due to the lack of complete information for a specific site of operation. Since conducting UCG trials and data extraction are costly and
