Paleofloral dependence of coal methane sorption capacity

The aim of this study is to reveal key physiochemical factors controlling gas sorption in coals during periods of dramatic coal deposition in Earth's history – the Upper Carboniferous (326–299 Ma) and Permian (299–252 Ma). As a starting point we developed a database of about 1000 entries, including coal-specific parameters such as proximate and ultimate analysis, sample origin, and specific surface area. Our study proposes an innovative approach...
