A high-volatile A bituminous coal was oxidized with 180, at 1OO'C for 72 h to simulate weathering, and subsequently pyrolysed at various temperatures to drive off C180,, C1801%, C1%,, C180, C160, Hz180, Hz'%. These gases were subsequently analysed by massspectrometry. The results indicate that 60%

A high-volatile bituminous coal possessing a high Gieseler fluidity and large dilatation was subjected to slight oxidation in air under chosen conditions. The resultant 'oxycoal'was treated with various chemical reagents in order to determine to what extent the original caking properties of this coa
As part of a study of self-heating tendencies of Australian coals and chars, the rates of oxidation of fresh and weathered chars and a weathered coal have been measured in dry (fresh char only) and moist air over the temperature range 45 to 94ยฐC. The oxidation of the weathered materials has an appar
