چکیده انگلیسی
Aim of this study was to evaluate the suitability of ensiled giant reed, ensiled maize, ensiled olive pomace, wheat bran for combined systems (CS: dark fermentation + anaerobic digestion (AD)) producing hydrogen-rich biogas (biohythane), tested in batch under basic operational conditions (mesophilic temperatures, no pH control). Substrates were also analyzed under a single stage AD batch test, in order to investigate the effects of DF on estimated energy recovery (ER) in combined systems. In CS, maize and wheat bran exhibited the highest hydrogen potential (13.8 and 18.9 NL kgVS−1) and wheat bran the highest methane potential (243.5 NL kgVS−1). In one-stage AD, giant reed, maize and wheat bran showed the highest methane production (239.5, 267.3 and 260.0 NL kgVS−1). Butyrate/acetate ratio properly described the dark fermentation, correlating with hydrogen production (r = 0.92). Wheat bran proved to be a promising residue for CS in terms of hydrogen/methane potential and ER.
