Author(s): M.Sajakulnukit, S.Mathurapot, P.Siriput, D.Janhorm, K.Suanchan, K.Nilkuha, T.SrinophakunHydrogen production using steam reformation from biogas as feedstock was designed, constructed and demonstrated. Biogas was gained from swine wastewater pond in Ratchaburi province, Thailand. This biogas was firstly cleaned by removingHydrogen sulfide;H2S, using Lo-Cat. Iron complex compound (Fe (III) EDTA) solution was reacted with hydrogensulfide ion. Then the complex compound was regenerated oxygen from the air. Carbondioxide was separated from biogas using molecular sieve as an adsorbent. The result showed that the outlet gas from cleaning system was comprised ofmethane 46.53%while H2S was less than 100 ppm.Next step, hydrogen gas was produced by steam reformation reaction with Ruthenium 5% on Alumina as catalyst which operated at 700-800ï‚°C. The gas product isH2 37.73%,CO20.38%andCH4 1.08%at the production rate of 50 liters per day.
