Firing Adaro, a subbituminous coal mined in Indonesia, can be a solution for emissions compliance because of its low sulfur, nitrogen and ash content and high volatile matter content, as can be seen in Table 1 where Adaro coal properties are summarized. Adaro coal has low sulfur content (%) compared to typical bituminous coals, which can eliminate installation of expensive desulphurization ...

In response to the shortages of coking coal, the grindingflotation separation process of coking middlings was proposed. Researchers considered that moderate comminution can improve the liberation degree and surface hydrophobic of coking middlings, and optimize the particle size distribution, thus enhancing the floatability [3,4,5,6]. However ...

The blended coal mass is heated for 12 to 20 hours for metallurgical coke. Thermal energy from the walls of the coke chamber heats the coal mass by conduction from the sides to the middle of the coke chamber. During the coking process, the charge is in direct contact with the heated wall surfaces and develops into an aggregate "plastic zone".

The idea of this paper is to properly utilize Indian lowrank coking coal (semicoking coal) with the blending of highrank imported coals and to reduce the overall cost of coke making. The blending of the coals has been done in two phases. Effect of blending mass ratio on the swelling index and plasticity parameters has been studied. The effect of maceral content, vitrinite reflectance, and ...

The coal pyrolysis is a fundamentally important process since it involves a set of chemical reactions, which play key roles in most coal conversion processes, such as coking, liquefaction, hydrogenation, gasification and combustion. The pyrolysis can be considered also as a test reaction for coals because of high sensitivity to coal properties.

Metallurgical coals fall broadly into two types (Figure 1). Coking coal is heated in the absence of oxygen in a coke oven to produce coke, which is then charged into blast furnaces as the key fuel and reactant. Coking coal can be further divided into hard coking coal (HCC), semihard coking coal (SHCC) and semisoft coking coal (SSCC).
