Investigation of Underground Coal Gasification in Laboratory Conditions: A Review of Recent Research
Publikováno v:
Energies, Vol 16, Iss 17, p 6250 (2023)
The underground coal gasification (UCG) technology converts coal into product gas and provides the option of environmentally and economically attractive coal mining. Obtained syngas can be used for heating, electricity, or chemical production. Numero
