The problems associated with assessing the catalytic effects of inherent mineral matter in coal during hydrogenation are discussed in detail. Preliminary results obtained from various relative density fractions of a South African high-mineral-matter coal are reported. Inert matter has been added in

Coals high in carbonate minerals show abnormally high VM on dmmf basis. This abnormality has been shown to be due to the presence of iron carbonate. Effects of the presence of different carbonate minerals on VM have been estimated, and a formula is advanced for estimating VM on dmmf basis of a coal

If coal is heated to 9OO"C, in the absence of air the organic coal substance and the associated mineral matter are decomposed. The analytically determined volatile-matter yield includes the volatile decomposition products of both the coal substance and the minerals. The correlation between mineral m
