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

Samples of a high-volatile bituminous coal were chlorinated with Cl, in various media. Two chlorination procedures were used: dry and wet chlorination. The wet method led to decreases in high and low temperature ash yields, while no significant changes in yield took place with the dry chlorination

Indigenous mineral matter in coal affects the chemical reactivity of resulting cokes through both catalytic graphitization and catalytic gasification. The significance of both catalytic effects on air-oxidation was examined using cokes from a medium-volatile bituminous coking coal with 9 wt% mineral

Activated carbons have been prepared from a semianthracite preoxidised in air to different degrees. The activation has been carried out in steam at 850Β°C to 5Ok 1% burnoff. The adsorption isotherms of nitrogen at 77 K and COZ at 273 K have been determined. The adsorption isotherms indicate that the
