Abstract

Nowadays, huge energy demand has become a critical problem in the world. Excessive utilization of fossil fuel as a primary source of energy brings about several crisis. Therefore, an alternative source of renewable energy, preferably biogas, production via anaerobic digestion technology has become the best solution for these energy issues. In this study, rice straw was used as the raw materials and mixed with 20% cow dung starter in batch type anaerobic digestion. Among the four different dilution ratios of straw and water (1:0.5, 1:1, 1:1.5 and 1:2 v/v), 1:1 ratio was the optimum for biogas production within 20 days period. The addition of nutrient, ammonium molybdate (0.01%, 0.02%, 0.03% and 0.04% w/v) to the anaerobic digester of optimum ratio of rice straw and water were studied and 0.02% w/v was observed to be the best for biogas production. The compositions of gases in biogas without nutrient were observed as 9.8% H2S, 20.2% CO2, 7.5% O2 and 62.5% CH4 and with (0.02% w/v) nutrient were observed as 0.1% H2S, 28.3% CO2, 1.8% O2 and 69.8% CH4. This nutrient addition method was improved the volume of biogas as well as the percentage of methane gas.
