Underground coal gasification (UCG): An analysis of gas diffusion and sorption phenomena
Fuel, 2015Abstract This article describes the results of measurements of the gas transport phenomena in coal and strata samples. The samples were taken from the surroundings of an underground georeactor in the “Barbara” Experimental Mine before and after an in situ underground coal gasification experiment.

Evaluation of coal resources for underground gasification in Poland. Selection of possible UCG sites
Fuel, 2017Abstract Several opinions are presented that underground coal gasification (UCG) may be used at large scale in coal seams of low thickness, at a great depth and for unrecovered coal in abandoned mines. Geological features of coal deposits limits wide application of UCG.

Abstract 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 ...

Abstract This paper presents the results of six tar sample analyses obtained during 60 days of an underground coal gasification (UCG) trial in the “Wieczorek” mine in Poland. The tars were sampled periodically during coal gasification by four different reagents: oxygen enriched air, air, a mixture of air and carbon dioxide, and air with nitrogen. The

Field test of large-scale hydrogen manufacturing from underground coal gasification (UCG)
International Journal of Hydrogen Energy, 2008Abstract The paper explores the reliability of using an underground coal gasification (UCG) technique for hydrogen manufacturing. Methods for increasing the temperature in underground gasifier are analyzed with the aim of improving the hydrogen-manufacturing process. In this paper, the rationales behind hydrogen manufacturing in UCG is explained. The

Abstract The UCG (underground coal gasification) trial was carried out at the Experimental Mine “Barbara” within the RFCS Project HUGE (2007–2010). The georeactor was placed in the coal seam 310 at the depth of 30 m. During the period of 15 days about 22 tons of hard coal was gasified with the average consumption rate of 62 kg/h.
