Catalytic pyrolysis of biomass waste using coal fly ash‐derived ZSM‐5 zeolite for enhanced bioenergy production

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Energy security and sustainability drive the exploration of innovative conversion strategies for abundant biomass waste into energy‐dense products (solid, liquid, and gaseous biofuels). This study demonstrated the catalytic potential of a coal fly ash (CFA)‐derived ZSM‐5 zeolite in enhancing biomass pyrolysis, focusing on lignocellulosic ...

Design of azine antioxidants for sustainable biodiesel: integrating structural characterization and molecular modeling

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract The growing global demand for sustainable energy solutions has intensified the search for renewable alternatives to fossil fuels, with biodiesel emerging as a promising candidate due to its biodegradability and lower emissions. However, its large‐scale application is limited by low oxidative stability, which compromises storage and performance.

Valorization of bark extracts from Cerrado and Amazon species: phenolic characterization, antioxidant capacity, and photoprotective potential for circular bioeconomy applications

Biofuels, Bioproducts and Biorefining, EarlyView.
Abstract Tree bark remains an underexploited source of high‐value‐added phenolic compounds with potential circular bioeconomy applications. This work characterized bark extracts from two species of distinct Brazilian biomes, Stryphnodendron adstringens (Cerrado) and Myrcia eximia (Amazon), obtained with three solvents (ethanol, methanol and acetone ...
