Seven kinds of coals (C, 77.S89.8 wt% daf) were oxidized with air at 150Β°C for 1, 5 and 10 h. The oxidized coals were heat-treated at various temperatures between 300 and 1500Β°C with intervals of 50 or 100Β°C. The pore-structure of the oxidized coals and the cokes or chars obtained from the oxidized

During the petrographic study of seven feed coals from different origins, it was found that these coals presented microfeatures such as: material size, shape, weathering, thermally affected particles and contamination. After devolatilization under fluidized bed conditions, some chars presented the c

In an effort to utilize the Sapozhnikov's plastometric test to evaluate Indian Coking coals, the authors have brought out, in two earlier publications, the significance of the profile features of the expansion pressure curves in supplementing the indices X and Y. A third parameter called profile len
