Abstract: Methods and systems for scrubbing and removing hydrogen sulfide from a biogas. The methods and systems use a hydrogen sulfide removal media comprising biomass derived biochar, activated carbon, silica gel, and metal organic framework inside a tube through which the biogas passes to scrub the hydrogen sulfide from the biogas. The methods and systems are capable of achieving are about 95% reduction of hydrogen sulfide present in the biogas.

Abstract: A method and system for enhancing methane generation in biogas production includes feeding cow manure and glucose into a semi-continuous stirring tank reactor. Incubating the cow manure and glucose to form waste activated sludge with methanogen growth. The methanogen growth is enhanced by surface areas of ferrous pebbles within the semi-continuous stirring tank reactor. Feeding rice husk and water into the semi-continuous stirring tank reactor. Mixing the rice husk, the water, and the formed waste activated sludge together to form a mixture. Initiating an anaerobic digestion process during the mixing to produce high volatile fatty acids. Increasing the production of the high volatile fatty acids to a higher level by enhancing adsorption of the methanogen microorganisms onto the ferrous pebbles. Reacting the higher level of the high volatile fatty acids with the ferrous pebbles to increase conversion of the higher level of volatile fatty acids to methane while producing biogas.
