Abstract

Kinetic study of plug flow reactor digesting corn silage was studied under the mesophilic condition (37 ± 2 °C). The effect of organic loading rate (OLR) on biogas yield and its production was tested in a long-term experimental study. Both the biogas yield (0.68–0.39 m³/kg) and methane content in the biogas (66–58%) were reduced with the increase in OLR (3.5–8.5 kg VS /m³٠d). In this study, the maximum biogas yield (y_m) as 0.716 m³/kg and first-order reaction rate constant (k) values as 0.0689 per day was obtained. The developed kinetic model could be used to design the dimension for a plug flow reactor digesting different organic wastes such as agricultural residue, animal manures, and biogas crops.
