ABSTRACT
This study evaluated the possibility of using granular activated carbon as support material for biohydrogen production in a continuous stirred tank reactor (CSTR). The CSTR was inoculated with aeration pre-treated sludge and operated at temperature of 36 °C and hydraulic retention time (HRT) of 6 h. It was found that both biogas and hydrogen yields increased with OLR at the range of 8-24 kg/m3.d. The biogas was mainly composed of CO2 and H2 with the percentage of H2 ranging from 38.4% to 41% in biogas. The maximum hydrogen production rate of 3.65 L was obtained in the reactor at OLR of 24 kg/m3d. The granular activated carbon could make the hydrogen-producing system stable regarding hydrogen production, pH value and microbial by-products and could be used as support material for fermentative hydrogen production.
