To study the effect of temperature using pretreated rice straw to generate biogas

The objective of this study was to investigate the effect of pretreatment and operating temperature during the anaerobic digestion by using rice straw as biomass. The experiment was conducted for 30days under both for mesophilic 30 to 40˚C and thermophilic 45 to 60˚C condition by continuous digestion process. Rice straw is a lignocellulosic biomass use as feedstock with to effect of pretreatment by NaOH was investigates for biogas generation. Quantity of biogas yield was reported as 0.73m 3 , hence pH level was 7.2 is obtained at 50˚C was achieved in 18 th day of thermophilic anaerobic digestion with respect 0.58for mesophilic digestion at 10 th
