Valorization of glycerol by ultrasound-assisted acetalization to solketal

Waste and Biomass Valorization
Abstract Conversion of glycerol into high-value chemical products is a compelling process in the biomass conversion and biorefinery industry. In this study, a novel approach was employed to investigate ultrasound-assisted solketal synthesis using glycerol and acetone as raw material and sulfated zirconia as catalyst.

Chlorella vulgaris biorefineries: sustainable biofuels and high‐value carbon capture

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Global reliance on fossil fuels has created urgent economic and environmental challenges, yet large‐scale use of algal biomass remains limited by production costs. Industrial scaling is constrained by inefficient harvesting and the technical challenges of processing recalcitrant cell walls.

Enzymatic synthesis of acylglycerides from agroindustrial residues: process design and simplified techno‐economic assessment

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract This study developed an enzymatic process to add value to palm oil fatty acid distillate (PFAD) and glycerol, resulting in the production of monoacylglycerides (MAG) and diacylglycerides (DAG). The biocatalyst loading (Novozym 435) and molar ratio of reagents were evaluated to obtain a suitable reaction condition in terms of space–time yield ...

Tuned Oxidation Potential of Continuous Defective Photocatalyst for Selective Biomass Conversion. [PDF]

Adv Sci (Weinh)
This work develops a wavelength‐controlled photocatalytic strategy that utilizes defect‐state excitation to modulate oxidative capability for biomass selective conversion. By tuning the photooxidation potential to match substrate reactivity, the system suppresses overoxidation and enables the selective formation of value‐added products, providing a ...
