Abstract

An adsorptionlreaction process for the purification of biogas prior to its use as energy vector L.V.-A. Truong & N. Abatzoglou Department of Chemical Engineering, University of Sherbrooke, Canada Abstract Biogas is produced both naturally in landfills and by fermentation of organic solid, semi-solid and liquid waste. When the biogas is valorized energetically it produces C02, which is approximately 20 times less "GHG" than CH4, its main combustible compound. Consequently, the most environmentally appropriate way for the management of biogas is its use for the production of energy. Raw biogas contains a number of undesired contaminants like H2S and NH3. The combustion of these contaminants produces SO, and NO,, known for their detrimental role in atmosphere and human health. This work presents the development at lab scale of a chemical adsorption technology for the removal of the H2S. The main phenomenon is an irreversible chemical reaction between the solid and the gas phases. The study produc
