Ultrasound-assisted bioalcohol synthesis: review and analysis

摘要: Sonication (or ultrasound irradiation) has emerged as a potential technique for the intensification of diverse physical/chemical/biological processes. In recent years, sonication been applied in synthesis liquid biofuels, such biodiesel, and bioalcohols, ethanol. The process bioalcohol comprises four steps, viz. acid pretreatment, alkaline delignification, enzymatic hydrolysis fermentation. Significant literature published last decade on application all steps synthesis. this paper, critical review analysis ultrasound-assisted presented. This addressed Essentially, areas biomass delignification reviewed, followed by an Finally, mechanistic investigations various have highlighting synergistic links between physical/chemical effects cavitation basic mechanisms not only demonstrated efficacy synthesis, but also brought to light underlying issues; could provide guidelines design optimization commercial scale
