TL;DR: In this paper, the authors studied the combustion behavior of two Indian coals of same rank with wide variation in mineral matter content using Thermogravimetric Analyzer (TGA) and Drop Tube Furnace (DTF).

TL;DR: In this article, the interparticle interactions of carbonaceous solids in water were determined on the basis of surface chemistries characterized by contact angle and ζ potential measurements, and the dominant interaction energies for such a system were observed to be 2-3 orders of magnitude higher than the electrostatic interaction energies and van der Waals interaction energies.

TL;DR: In this article, the effect of the additive on the interfacial interactions which results in viscosity reduction in carbonaceous solid-water slurries (CSWS) was determined. But the focus of this study was to determine the effect on the additives on the carbonaceous solids, the change in the zeta potential and hydrophobicity/hydrophilicity of the solids and change in free water content of the slurries.

TL;DR: In this paper, the burning behavior of coals of Indian origin by TGA and in drop tube furnace (DTF) with particular emphasis on the role of macerals and their associations was investigated.

TL;DR: In this paper, a thixotropic model taking into account particle aggregation was found to predict viscosity more accurately in the case of these hydrophobic carbonaceous solid-water slurries.
