Abstract
The objective of this paper is to investigate the effect of temperature on anaerobic digestion of two very common lignocellulosic biomasses such as rice husk and rice straw. Rice husk and rice straw are abundant in south East Asia. They are not effectively used for any fruitful purpose rather they are disposed of in the open environment polluting the atmosphere and causing serious health problem. In this paper the rice husk and rice straw were first characterized to see their potentiality for biogas production and then pretreated to make the biogas production achievable. The anaerobic digestion was considered at three different operating temperatures, namely, 45 °C, 50 °C and 55 °C, respectively. Effect of temperature on kinetic rate constant was also studied. It was observed from the investigation that biogas production increases with increase in temperature. The kinetic rate constant plays a significant role to indicate the digestion process.
