Abstract
Lignocelluloses are often a major or sometimes the sole components of different waste streams from various industries, forestry, agriculture and municipalities. Hydrolysis of these materials is the first step for either digestion to biogas (methane). However, enzymatic hydrolysis of lignocelluloses with no pre-treatment is usually not so effective because of high stability of the materials to enzymatic or bacterial attacks. The reason for improved rate of hydrolysis by removal of lignin might be related to a better surface accessibility for enzymes by increasing the population of pores after removing of lignin. We used acid, alkali, thermal methods for pre-treatment of jatropha deoiled cake, treated jatropha cake biomass was anaerobic ally digested to biogas in lab scale stirred tank bioreactor(figure1) at fixed conditions as shown in table 1. The present work deal with different pre-treatment’s method for delignification of jatropha deoiled cake at different conc of acid ,alkali for different interval of time . Further, as per analysis it was seen that alkaline hydrolysis can be a good method for delignification of jatropha deoiled cake as compare to acid and thermal methods. However, the yield of methane content in biogas obtained was found maximum after acid treated biomass (85.72% methane) as compared to alkaline treated biomass (81.12% methane)and thermal treated biomass (79.36%methane).
