Volatile-char interactions during biomass pyrolysis: Effect of char preparation temperature

Bin Li et al.

Summary: This study experimentally investigated the effect of char preparation temperature on the interactions between cellulose volatiles and acid-washed sawdust char, revealing that changes in biochar chemical structure caused by different preparation temperatures significantly impacted the final products of cellulose pyrolysis. Lower temperature chars exhibited higher reactivities, and volatile-char interactions altered the product distribution.

Heterogeneous activation of persulfate by carbon nanofiber supported Fe3O4@carbon composites for efficient ibuprofen degradation

Yang Zhang et al.

Summary: Heterogeneous catalysts for persulfate activation were synthesized using a one-pot hydrothermal method with ferrocene and carbon nanofiber as precursors. The catalysts exhibited high catalytic performances for ibuprofen degradation, with stable activity and minimal metal leaking over multiple cycles. Hydroxyl and sulfate radicals were identified as the main contributors to ibuprofen degradation, with the possible pathways elucidated through intermediate analysis.

Magnetite-contained biochar derived from fenton sludge modulated electron transfer of microorganisms in anaerobic digestion

Mingwei Wang et al.

Summary: A new magnetite-contained biochar was prepared using iron-rich Fenton sludge as raw material, with the transformation of amorphous iron oxides into magnetite at 400 degrees C of pyrolysis and preservation of redox quinone/hydroquinone moieties of biochar. This magnetic biochar exhibited high capacitance and excellent conductivity, leading to significantly enhanced methane production when supplemented into anaerobic digestion system, offering a new approach to recycle hazardous Fenton sludge.

Rhamnolipid pretreatment enhances methane production from two-phase anaerobic digestion of waste activated sludge

Qiuxiang Xu et al.

Summary: The study demonstrates that rhamnolipid (RL) pretreatment has a promoting effect on methane production in two-phase anaerobic digestion of waste activated sludge, although methane production may be inhibited in the presence of RL during the acidogenic phase. Further analysis shows that the addition of RL can increase methane production throughout the entire two-phase anaerobic digestion process.

Improving nutrients removal and energy recovery from wastes using hydrochar

Lan Wu et al.

Summary: Hydrothermal carbonization (HTC) is an eco-friendly, flexible, and efficient method to valorize wet solid wastes, producing carbon-rich hydrochar. Research has focused on the impacts of hydrochar on energy recovery, nutrient reclamation, and wastewater treatment, while also analyzing the influence of hydrochar type on its application. Studies have quantitatively summarized the benefits of using hydrochar in anaerobic digestion and as a slow-fertilizer for plant growth, as well as evaluating its effectiveness as an adsorbent for remediating pollutants from wastewater. Challenges and opportunities for future applications of hydrochar in waste management are also discussed.
