Abstract

This paper reports on biogas production by anaerobic digestion of Jatropha curcas seed cake in semi-continuous flow at 30°C, focusing on increasing the organic loading rate (OLR) of seed cake by investigating levels of 1.25, 1.67, 2.5, 3.33 and 5 kg Chemical Oxygen Demand (COD)/m³ day. Reactors were fed at flow rates of 125, 167, 250, 333 and 500 ml/day, yielding Hydraulic Retention Times (HRTs) of 40, 30, 20, 15 and 10 days. Increasing the OLR decreases the organic digestion. The highest methane yield (340 l at STP/kg COD degraded) was obtained at the OLR of 1.25 kg COD/m³day. © 2010 Inderscience Enterprises Ltd.
