Induced Bed Reactor (IBR) - Methane Gas Production

Technical Summary

•  Dr. Conly Hansen of Utah State University’s food sciences department has developed an induced bed reactor (IBR) for producing and capturing methane biogas for fuel use.

•  As biomass is produced and collected, it is placed into the IBR. An auger passes through the aperture of a septum and turns slowly to keep solids from accumulating in the aperture. Bacteria begin to react with the anaerobes, forming methane molecules from the reaction with the methanogen. These bacteria then float upward and collide with the septum, resulting in the release of CH4 molecules. These molecules continue upward through the aperture of the septum resulting in capture and storage of the gas. The bacteria then fall back to the bed of biomass to further react with methanogens to produce methane gas.

 

Commercial Applications

•  Waste can be used to produce energy on site

•  Processes most bio-solids

•  Potential commercial partners:

•  Farmers and agriculture

•  Food processing plants

 

Competitive Advantages

•  IBR takes 5 days to digest instead of 30 or more days

•  Less expensive than complete mix method

•  Fast and more reliable than conventional systems

•  Cuts down on odor and reduces fly population

•  Environmentally friendly – reduces CH4 in atmosphere

•  Renewable energy source
