Latest Patents

Liang Yu holds a patent for a two-stage anaerobic digestion system. This system is designed to produce biogas, specifically methane, through a unique process. The first stage involves a first reactor where anaerobic microbes are cultured in two phases: a high solids phase and a low solids phase. The second stage utilizes a methanogen-rich anaerobic culture in a low solids medium within a second reactor. This innovative design allows for the effective removal of effluent that comprises pH-lowering reaction products, which helps maintain a suitable pH in the high solids phase. Additionally, the transfer of effluent from the second reactor to the first reactor aids in mixing and reseeding the high solids phase with methanogens. Methane is produced and recovered from both reactors, showcasing the efficiency of this system.
