摘要： 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.
