2018/8/1/ · The anaerobic fermentation experiments were carried out at a temperature of 35 °C and the entire process lasted 30 days. Biogas slurry was sprayed twice a day for a minimum of 30 min each through a dump pump to increase heat and mass transfer. Biogas residues were collected after 30 days of anaerobic fermentation and then composted.
2023/2/1/ · Marsh gas or biogas is produced from biomass fermentation. Biogas is produced because of the lack of oxygen and the activity of anaerobic bacteria, especially methanogens, in a fermentation chamber [13], [14]. The resulting gas is odorless, colorless, and flammable and has a blue flame without smoke when burning.
