| description | One of the most effective technologies involving the use of lignocellulosic biomass is the production of biofuels, including methane-rich biogas. In order to increase the amount of gas produced, it is necessary to optimize the fermentation process, for example, by substrate pretreatment. The present study aimed to analyze the coupled effects of microwave radiation and the following acids: phosphoric(V) acid (H<sub>3</sub>PO<sub>4</sub>), hydrochloric acid (HCl), and sulfuric(VI) acid (H<sub>2</sub>SO<sub>4</sub>), on the destruction of a lignocellulosic complex of maize silage biomass and its susceptibility to anaerobic degradation in the methane fermentation process. The study compared the effects of plant biomass (maize silage) disintegration using microwave and conventional heating; the criterion differentiating experimental variants was the dose of acid used, i.e., 10% H<sub>3</sub>PO<sub>4</sub>, 10% HCl, and 10% H<sub>2</sub>SO<sub>4</sub> in doses of 0.02, 0.05, 0.10, 0.20, and 0.40 g/g<sub>TS</sub>. Microwave heating caused a higher biogas production in the case of all acids tested (HCl, H<sub>2</sub>SO<sub>4</sub>, H<sub>3</sub>PO<sub>4</sub>). The highest biogas volume, exceeding 1800 L/kg<sub>VS</sub>, was produced in the variant with HCl used at a dose of 0.4 g/g<sub>TS</sub>. |
