Ultrasound-assisted low-temperature catalytic lignin-first depolymerization of pine wood biomass to selectively produce propyl guaiacol

Abstract

Lignin-first depolymerization of biomass using reductive catalytic fractionation (RCF) to valorize lignin while impeding the loss of the carbohydrate fraction in it is a potential resource recovery strategy for the...

Robust pretreatment in combination with ultrasound-assisted surfactant to improve the enzymatic hydrolysis of Eucalyptus pellita

“…The results showed that ultrasound acoustic cavitation could enhance the depolymerization of lignin, thus greatly enhancing the production of liquid fuels (Du et al 2020). Prabhudesai et al employed an ultrasonic pretreatment of the pine wood and the degree of delignification and the selectivity enhanced towards lignin monomers significantly (Prabhudesai et al 2023). Olguin-Maciel et al did a study on ultrasound pretreatment of non-conventional starch at different sonication temperature conditions (45, 70, and 90 °C).…”
