In this article, the results from a pilot-scale, underground coal gasification (UCG) experiment conducted in an operating coal mine “Wieczorek” were presented. The 60-day gasification trial demonstrated that through the appropriate selection of the test site and by applying all safety standards essential for the coal mining industry, UCG in an active mine can be conducted safely and efficiently. The...
The main objective of this study was the assessment of the feasibility of applying the underground hard coal gasification in the production of a hydrogen-rich gas. In the course of the experiment the so-called two-stage gasification process in which oxygen and steam were supplied to the reaction zone separately in alternate stages was investigated. For this purpose a special surface reactor has been...
The main goal of the study presented in the paper was to experimentally demonstrate the feasibility of lignite gasification to hydrogen-rich gas under the underground conditions simulated in the ex situ reactor. The in situ gasification conditions were simulated both in respect to the coal seam and the surrounding stratum. In the 54-h experiment the process of lignite gasification with oxygen and...
