Transforming Coal Waste into Surface‐Engineered Carbons for Lithium–Sulfur Batteries

Batteries &Supercaps, EarlyView.
Coal waste is transformed into surface‐engineered porous carbons that suppress polysulfide shuttling and boost Li–S battery performance. Slow redox kinetics and polysulfide shuttling hinder the practical deployment of lithium–sulfur (Li–S) batteries.

Energy Balancing of Electrochemical Alternatives to the Solvay Process

Chemie Ingenieur Technik, EarlyView.
To overcome the CaCl2 and CO2 emissions custom to the conventional Solvay process in soda ash production, electrochemically based alternatives were investigated. In particular, the mass‐ and energy balances for chlor‐alkali electrolysis and bipolar electrodialysis‐based processes are discussed comprehensively in the presented work.

Integrated and closed‐loop biorefinery strategies for efficient waste valorization and biofuel production

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Advancements in biofuel production technologies are essential for reducing global dependence on fossil fuels and addressing their overexploitation. Many valuable components of biomass, such as cellulose, hemicellulose, and lignin, remain underused in traditional biorefineries, which typically rely on a single feedstock to produce a primary ...

Coal and gas outburst prevention using new high water content cement slurry for injection into the coal seam

International Journal of Mining Science and Technology, 2017
As coal and gas outburst is one of the most serious mine disasters, it is very important to at least control it if not prevent it from occurring. Injecting cement slurry or grouting into the coal seam can strengthen the seam, increase its rigidity ...
