Abstract
AbstractSeveral Australian oil shales were analysed using in‐situ high‐temperature XRD in four different environments (air, N2, CO2, and vacuum). The types of reactions that occur during heating of the oil shale depend on factors such as the heating environment and the heating rate, Dehydration and decomposition reactions are more prominent in a vacuum environment, compared to the possible other reactions. However, it was noted that oxidation reactions such as pyrite to pyrrhotite transformation, are not totally suppressed in vacuum and nitrogen, although the extent of the reactions is comparatively small. Under oxidation conditions, pyrite is converted to iron oxides, emitting SOI in the same temperature range as kerogen is converted to oil. Although carbon dioxide partially impedes the decomposition of carbonate minerals such as calcite, formation of CaSO4 is not significantly afected. Therefore, adsorption of environmentally problematic SO2 gas by CaO can still be achieved in CO2 environments.
