The Underground Coal Gasification Process in Laboratory Conditions: An Experimental Study

The underground coal gasification (UCG) process represents a modern and effective mining technology that enables energy extraction through thermic decomposition. is transformed into syngas by oxidizers (e.g., air, technical oxygen, or water steam) injected georeactor. produced exhausted on the surface, where it desired form of energy. This paper presents an experimental study two experiments performed in ex-situ reactors. describes equipment for UCG process, physical models seam, analysis coal. obtained results from are presented as behavior temperatures during experiment, composition, its calorific value. material balance time were also identified individual experiments. aim was to evaluate impact seam model efficiency. Calculating appears be tool assessing leaks reactor while measuring flow concentration gas. data make possible propose methods controlling input oxidizers. To increase efficiency reactor, necessary ensure impermeable poorly permeable surrounding layers seam.
