Abstract
Biogas is a clean renewable energy source which can be directly substituted in place for conventional fossil fuel. Regrettably, biogas often contains a large amount of H2S which must be removed for its effective usage. The focus of this study was to assess potential of local biogas production on Long Island, NY and develop a cost-effective and environmentally friendly technology for removal of H2S in a biogas stream. An assessment of the biogas potential found that 234 x 106 m3 of CH4 can be locally produced, which is equivalent to 2.54 TW-h of electricity, approximately 12% of fossil fuel power generation of Long Island. Biochar produced from hardwood, switchgrass, rye, and animal waste was evaluated as a potential adsorbent of H2S. Samples were characterized and activated under CO2 and O2. Prior to activation biochar samples exhibited limited H2S adsorption capacity, but this improved by over 88% after activation. The maximum surface area (1103 m2g-1) was attained at 850
