TL;DR: In this paper, the effect of two newly developed anionic additives in the formulation of coal-water slurry (CWS) has been studied, and the results showed that coal loadings to the extent of 70% in the CWS have been achieved using a concentration of 0.8 wt.% (on coal charge) of the naphthalene-based additive referred to as ‘P’.

TL;DR: Thermal treatment technologies were compared to determine an appropriate method of recovering energy from two wastes - spent mushroom compost and coal tailings and fluidised-bed combustion was more efficient than the packed-bed in both instances and pellet combustion was superior to that of the compost alone.

TL;DR: In this paper, the authors reported the formulation of highly concentrated coal−water slurry using a natural occurring surface active compound, saponin, extracted from the fruits of plant Sapindous laurifolia.
Abstract: Coal−water slurry has received considerable research nowadays due to its ability in substituting energy sources. The present work reports the formulation of highly concentrated coal−water slurry using a natural occurring surface active compound, saponin, extracted from the fruits of plant Sapindous laurifolia. The isolation of saponin from the plant and its surface activity has been discussed. The rhelogical characteristics of coal−water slurry have been investigated as a function of coal loading, ash content of coal, pH, temperature, and amount of saponin. The viscosity of the slurry and zeta potential are substantially decreased with concomitant shift of the isoelectric point of coal on adsorption of saponin to it. In the presence of 0.8% of saponin, coal−water slurry containing 64% weight fraction of coal could be achieved. The slurry is stable for a period of as long as 1 month in contrast to 4−5 h in the case of bare coal−water slurry. The results confirm the use of saponin as a suitable additive for...

TL;DR: In this paper, a long side-chain polycarboxylate (LcPC) was designed as a dispersant for coal-water slurry (CWS) and synthesized in aqueous solution from the copolymerization of macromonomer polyethylene glycol-acrylate monoester(PA), sodium p-styrene sulfonate (SSS), and acrylamide (AM).
