Biomethanation of blast furnace gas using anaerobic granular sludge via addition of hydrogen

The high concentrations of CO (toxic) and CO(2) (greenhouse gases) in blast furnace gas (a by-product of steelworks) reflect its low calorific value. In this study, anaerobic granular sludge was used to convert carbon from blast furnace gas to methane via exogenous hydrogen addition. The inhibition...

description The high concentrations of CO (toxic) and CO(2) (greenhouse gases) in blast furnace gas (a by-product of steelworks) reflect its low calorific value. In this study, anaerobic granular sludge was used to convert carbon from blast furnace gas to methane via exogenous hydrogen addition. The inhibition of methane production by CO partial pressure (P(CO)) was found to start from 0.4 atm. The intermediate metabolites from CO to methane including acetate, propionate, and H(2) accumulated at higher CO concentrations in the presence of 2-bromoethanesulfonic acid. After the introduction of H(2) and blast furnace gas, although the hydrogen partial pressure (P(H(2))) up to 1.54 atm resulted in the maximum CH(4) yield, the whole system was not stable due to the accumulation of a large amount of volatile fatty acids. The optimum P(H(2)) on CH(4) production from the simulated blast furnace gas, 5.32 mmol g(−1) VSS, was determined at 0.88 atm in this study.
