Abstract

Two coals (Beulah, PSOC-1483, and a Thai coal, TH23) of unusually high reactivity with hydrogen and tetralin were shown to contain significant methoxy group contents. The fate of the methoxy groups when these coals were reacted under N₂ at 320°C (with and without added decalin) and with H₂-tetralin and H₂SnO₂ at 405°C was studied. The reactions of TH23 coal gave unexpectedly high water yields. Reactions of model compounds containing methoxy groups under similar conditions also gave high water yields. Proton magnetic resonance thermal analysis (PMRTA) confirmed that TH23 host and guest coal components are structurally distinct from those of Loy Yang (Victoria) run-of-mine coal.
