dc.description.abstractA biological process is proposed for the recovery of sulphur from hydrogen sulphide hearing gas. The process involves absorption of the gas in an aqueous, ferric sulphate solution wherein, it is converted to elemental sulphur and ferric is reduced to ferrous. Oxidation of ferrous sulphate, which is a rate determining step, is carried out using Thiobacilluss ferrooxidans as catalyst, immobilized on a Carbon support in a fluidized bed reactor. The experiments are carried out in both batch and continuous modes of operation. The effects of various parameters such as light, ammonium sulphate, urea, and carbon dioxide as additives, have been studied to get better insight into the process of oxidation of Fe 2+ to Fe3+. The absence of light and the addition of ammonium sulphate improved the oxidation rate of Fe2+. The use of urea as an additive showed substantial enhancement of the oxidation rate. As the catalyst loading is increased, the oxidation rate of Fe2+ is also increased. The performance of the reactor in continuous mode of operation has been evaluated at different flow rates of Fe2+ solution. Sulphur of high purity has been obtained from H2S gas. The reduced solution is then oxidized to ferric sulphate and reused partly in order to simulate commercial operation.en_US
