TL;DR: In this article, two brown coals from China were dewatered under hydrothermal dewatering (HTD) conditions at 250-320°C for 1h in a 2L autoclave.
134 citations
TL;DR: In this article, the authors analyzed the properties of slurryability, rheology, stability and fluidity of petroleum coke and petrochemical sludge slurry and found that the sludge produced a significant effect to improve slurry stability.
83 citations
TL;DR: In this paper, the effects of sludge type, sludge mixing proportion (α ), and sludge particle size on rheology and thixotropic properties were assessed, indicating that the sludge enhances the pseudoplasticity and the thixotropy of the slurry.

TL;DR: In this article, coal-sludge slurry (CSS), which is made by blending sewage sludge with coal, water, and additives, is identified as a new and effective sludge utilization technology.
Abstract: Municipal sewage sludge always includes considerable amount of water, noxious substances, and varying chemical compositions; therefore, sludge utilization is imposed. Coal-sludge slurry (CSS), which is made by blending sewage sludge with coal, water, and additives, is being identified as a new and effective sludge utilization technology. The main objectives of the present investigation are research on the slurrying, rheology, and stability properties of five CSSs, and determine the influence of sludge type, sludge mixing proportion (α), temperature, and shear rate on the slurrying properties that play a critical role in CSS technology. Results showed that (i) the maximum solids loading (MSL) dropped sharply with the rise of α, ranging from 55.22% to 59.41% in the α = 15% case, compared to 69.16% in the α = 0 case; and (ii) the apparent viscosity dropped as the temperature rose from 20 °C to 50 °C, in an approximate linear correlation. All CSSs exhibited a pseudo-plastic rheology, and increasing ω and α re...
