Combustion of pipelineable coal-water slurries

, 1991
The use of liquids or fluids to transport coal through pipelines is not new, nor is the application of coal liquid slurries as fuels in industrial combustion systems. However, it does appear that there are a number of conflicting areas which preclude coals from performing well in a pipeline transportation mode and as a coal-liquid fuel (CLF).

Upcycling Cotton–Polyester Textile Waste Into High Quality Biochar and Activated Carbon for Energy Storage Applications

Energy Technology, Volume 14, Issue 11, November 2026.
Mixed cotton–polyester textile waste is transformed through pyrolysis and KOH activation into high‐surface‐area carbons for energy storage. The blend produces the most porous biochar, while cotton‐derived activated carbon reaches 2537 m2/g and 112 F/g. These results reveal how textile composition governs pore development and supercapacitor performance,

Mechanisms of the effects of external fields and polycarboxylic acids on the performance of gangue-based non-cementitious filling slurry

Case Studies in Construction Materials
This study focuses on the non-cementitious filling technology for underground coal mines, where the filling slurry is prepared using coal gangue as the aggregate, supplemented by fly ash. Based on the slurry ratio determined in the preliminary tests, the
