    Abstract

    The experimental study was carried out on anaerobic digestion of jatropha (Jatropha curcas) and pongamia (Pongamia pinnata) oil seed cakes in a 20m3/d capacity floating drum biogas plant under mesophilic temperature condition. The average specific methane production potential of jatropha oil seed cake was observed as 0.394m3/kg TS and 0.422m3/kg VS. The average content of methane and carbon dioxide in the produced biogas over 30days of retention time period was found as 66.6% and 31.3%, respectively. Cumulative methane yield over 30days of retention time period was found as 131.258m3 with a 259.2kg of input volatile solids, with an average total volatile solids mass removal efficiency of 59.6%. However, in case of pongamia oil seed cake average specific methane production was observed as 0.427m3/kg TS and 0.448m3/kg VS. The average value of methane and carbon dioxide content in the produced biogas over 30days of retention was found as 62.5% and 33.5%, respectively. Cumulative methane yield over 30days of retention time period was found as 147.605m3 with a 255.9kg of input volatile solids, with an average total volatile solids mass removal efficiency of 74.9%.
