ABSTRACT:

 Study on size effects of corn stalks for biogas production was evaluated for three different sizes of stalk: 15 - 20 cm, 8 - 10 cm and 1-2 cm. The 21L anaerobic digesters were set up to implement experiments in laboratory conditions. All experiments were fed with loading ratio of 1 kg vs/m^ct1, the hydraulic retention time was 60 days. The control parameters from all experiments (temperature, pH) were not significantly different between treatments but ranged in suitable values for anaerobic fermentation processes. The biogas yield and CH4concentrations were highest at treatment with sizes 8-10 cm, the next was treatment of 1 - 2 cm and the lowest was treatment of 15 - 20 cm with 526 L/kg vs - 38.3%, 440.5 L/kg vs - 29.2% and 312.2 L/kg VS-26.4% in respectively. The %CH4 ofall treatments tended to increase by day and kept more stable in treatment with size 8- 10 cm than the rest. The results show that using com stalks in size 8- 10 cm produced more biogas than other sizes. Using com stalks for biogas production help farmers improve their life conditions.
