چکیده انگلیسی
Although a novel anaerobic down-flow structured bed reactor has shown feasibility and stable performance for a long-term compared to other anaerobic fixed bed systems for continuous hydrogen production, the volumetric rates and yields have so far been too low. In order to improve the performance, an operation strategy was applied by organic loading rate (OLR) variation (12-96 g COD Lâ1 dâ1). Different volumetric hydrogen rates, and yields at the same OLR indicated that the system was mainly driven by the specific organic load (SOL). When SOL was kept between 3.8 and 6.2 g sucrose gâ1 VSS dâ1, the volumetric rates raised from 0.1 to 8.9 L H2 Lâ1 dâ1, and the yields were stable around 2.0 mol H2 molâ1 converted sucrose. Furthermore, hydrogen was produced mainly via ethanol-type fermentation, reaching a total energy conversion rate of 23.40 kJ hâ1 Lâ1 based on both hydrogen and ethanol production.
