Investigation of Thermal Effects on Samples of Coals to Determine the Prospect of Their Utilization as Sources of Gaseous Fuels

One of the promising ways of expanding energy resource base is production of combustible gas from coalbeds. The yield of gaseous components from samples of Visean coals of Tatarstan upon thermal impact was studied in this work by combined thermogravimetric and IR spectrometric method. It is demonstrated that methane begins to appear actively at 384-405°C, depending on the test coal sample. In this process, the yield of methane could be as much as 30 wt. % and higher, which confirms the prospect of getting gaseous fuel from Visean coal deposits by thermal impact.
