In order to remove hydrogen sulfide from petroleum refinery, a fixedbed bioreactor was constructed by the immobilized Thiobacillus ferrooxidans (T.f ) with H-3 carrier. In the state of bioreactor operation, a maximum Fe 2C oxidation of 7.24 g/L.h was attained with the aeration of 300 L/h, the dilution rate of 0.6 h 1 , the pH of 2.0, and the temperature of 30 ı C. And the complex compound forming on the surface of the carrier in the operation of bioreactor was identified as jarosite by chemical analysis and X-ray diffraction analysis. In the fixed-bed bioreactor, the removal of hydrogen sulfide was higher than 99.12%, and the content of H 2 S in the exhaust was less than 10 g/g.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
