Abstract

Experiments involving coal pyrolysis with subsequent capture and analysis of the devolatilised ‘tar’ products is presented, with the aim of providing information pertinent to developing groundwater risk assessments for underground coal gasification (and similar in-situ thermal process). Different coals were pyrolysed at different temperatures and for different lengths of time within a reactor, and the resultant volatilised components were captured by condensation and analysed by GC-MS for PAHs and phenols. Whilst a clear correlation was found between temperature and amounts of potential contaminants in the condensates, there was no clear correlation with the residence time of the parent coal within the furnace.
