Modelling the methane production from corn silage pretreated with White Rot Fungi

Popis výsledku v původním jazyce

Abstract from conference. Anaerobic digestion is an efficient energy-generation process converting an organic material in an energy-carrying gas, known as biogas, and a solid residue (digestate) [1]. To date, the solid by-product was mostly used in agriculture for soil amendment [2]. The enhanced number of biogas plants and the polluting potential of the generated digestate necessitate the development of sustainable, economically attractive and safe techniques for the treatment and utilisation of the digestion waste.Pyrolysis constitute an attractive alternative for digestate handling. The number of applications of the generated biochar could improve the economics of an anaerobic digestion plant [3]. Biochar reduces soil erosion and can partially substitute the inorganic fertilizers due to its nutrients content, whereas preserves water quality by hindering nutrient leaching. Due to the porous morphology, biochar promotes anaerobic digestion microorganisms&apos; activity and thereby it can also be used as a supporting agent in a digester for enhancing the efficiency and shortening the instable start up period [4]. On the other hand, the generated pyrolysis oil contains a great amount of organic substances that can potentially be used for production of fuels and chemicals.In the present study, the solid by-product of an industrial biogas plant operating with agricultural residues under mesophilic conditions was treated by means of isothermal pyrolysis under three different temperatures of 300-500 oC to investigate the effect of pyrolysis conditions on biochar and biooil properties.
