Abstract: The efficiency of biogas is affected by the presence of Hydrogen sulphide, which is a highly toxic and corrosive gas. The purpose of this work was to investigate the removal of Hydrogen sulphide from biogas by the addition of chelating ligands under real-time operating conditions. A number of experimental analysis were carried out which involved the use of Biogas 5000 analyser and other classical analytical tools. The results from these analyses showed a general decrease in Hydrogen sulphide concentration from 30% to 80% on increasing the concentration of deferoxamine mesylate from 10 µM to 100 µM. Although increasing the concentration reduced the percentage of Methane gas produced, it resulted in an increased volatile fatty acid concentration which is the major cause of the decline in methane gas yield observed. Trace metals like Iron, Cobalt and Nickel within the digester system, react with deferoxamine mesylate to form metal chelates which eventually undergo a redox reaction with the Hydrogen sulphide gas to produce elemental Sulphur with the release of H+ ions; thus reducing the concentration of Hydrogen sulphide within the digester systems.
