Microwave- Versus Conventional Acid-Assisted Thermohydrolysis of Willow and Maize Silage: Methane Yield and the Energy Cost of Pretreatment
Hydrothermal pretreatment is widely proposed to improve the anaerobic digestibility of lignocellulosic biomass, yet whether it repays its own energy input is rarely quantified. We compare microwave- and conventional (conductive) acid-assisted thermohydrolysis of willow (Salix viminalis) and maize silage at 110–130 °C,...
