Adsorption Desulfurization of Liquid Fuel Using a Blend of Date Stones and Walnut Shells by Box–Behnken Design

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT A specific microporous KOH/activated‐biochar (K/BC) was produced from a blend of date stones (DS) and walnut shells (WS) and used in the adsorptive desulfurization (ADS) of two types of model fuel DBT/n‐hexane (S‐hex), DBT/cyclohexane (S‐cyclohex).

The Effect of Demineralization on Coal Functional Group Pyrolysis: Rank‐Dependent Dual Mechanisms of Structural Reorganization and Mineral Catalysis

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Coal pyrolysis, as a key thermochemical conversion process, is significantly influenced by inherent minerals, yet their role across different coal ranks remains inadequately understood. This study investigates the effect of acid‐washing (demineralization) on the thermal decomposition of six functional groups (aliphatic C–H, aromatic C–H/C=C, C=

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.
