Hydrodynamic cavitation (HC), which can effectively induce sonochemical effects, is widely considered a promising process intensification technology. In the present study, HC was successfully utilized to intensify alkali activation of GPs for SCs, first time. Five BDCMs were synthesized following method reported in literature. For comparison, four more with HC-treated, among sample further doped nitrogen during treatment, prepared. Then all samples compared from microscopical characteristics electrochemical performance as SCs materials. The morphology study demonstrated that treatment had created many defects and amorphous carbon structures on GP-based BDCMs, highest SSA reaching 3272 m2/g (1:6-HCGP), 32 folded Raw sample's. also intensified N-doping process. XRD XPS results manifested N content been increased consequently changed electronic structure atoms, leading increase specific capacitance (1:6-HCGP+N-based SC, 227 F/g at 10 A/g). cycle proved have long-term stability, indicating HC-treated good choices energy storage technologies. Compared ultrasound-assisted method, may high density, HC-assisted enables production efficiency. This work time attempt towards industrial application energy-related materials synthesis encourages in-depth studies future.

Renewable deep eutectic solvents pretreatment improved the efficiency of anaerobic digestion by lignin extraction from willow

Energy Conversion and Management, Journal Year: 2023, Volume and Issue: 288, P. 117115 - 117115

Published: May 15, 2023

Lignin extraction from lignocellulosic biomass can enhance its bioconversion efficiency, whilst the recovered lignin provide added economic value. This study comprehensively investigated impacts of short-chain carboxylic acid-based deep eutectic solvents (DESs) pretreatments on willow and assessed subsequent biomethane production through anaerobic digestion. Process parameters (including DESs type, molar ratios components, temperature reaction time) in for were optimized using central composite surface response methodology. Results showed that lactic DES pretreatment outperformed acetic acid propionic terms removal efficiency methane production. Under optimal conditions (choline chloride:lactic with a ratio 1:10 at 160 °C 15 min) retained over 94% glucan content raw achieved highest 80%. The purity above 81%. Compared 89.9 mL/g total solid willow, significantly increased by 36.3% after pretreatment. condition reduced digestion time 22 to 10 days. overall energy conversion 62.7% demonstrated lignocellulose could be promising method co-produce renewable gaseous fuels sustainable approach.
