abstract="Results in a microcalorimeter for a UK anthracite coal at temperatures of 60 and 70°C are found to display a considerable spread which is tentatively attributed to petrographic variations between the samples. Results are compared with previously reported ones for a low-rank coal in the same instrument at lower temperatures.<p /><p>Language: en</p>",
