Abstract:
Napier grass is fast-growing, high-yield, easy harvesting and highly abundance in Thailand. Therefore, the biogas production potential was studied in this work to examine the feasibility of Napier grass in anaerobic fermentation. The Pennisetum purpureum x Pennisetum americanum (Napier Pak Chong 1) was used as the organic materials substrate for biogas production under an anaerobic fermentation. The batch fermentation was tested in a 1,000 ml glass bottle with a working volume of 400 ml. In this experiment, cow manure was used as the inoculum. The ratio of inoculum and organic materials substrate was 1:2. The glass bottle was operated in the temperature-controlled room at 35±2 °C for 60 days. The influent and effluent were analyzed for pH, COD, TS, and TVS. These parameters were used to analyze correlations of the biogas production rate and the working volume in the batch fermentation. The cumulative volume of biogas produced was used to measure the fermentation performance. The study found that Napier grass revealed accumulative biogas production of 496.2 ml/gVSadded with methane content of 55.1%.
