Abstract
For production of biofuels from woody biomass, an initial pretreatment step is required for removal of lignin prior to enzymatic saccharification. In the present study, ameliorating effects of peroxometal complexes on delignification of beech wood have been studied using external (autoclave) heating and microwave irradiation. The results clearly show that ammonium molybdate, when transformed to peroxometal complex by hydrogen peroxide (H2O2), exhibits potent delignification property. The beech wood gave sugar yield of 69 and 41.8% after microwave irradiation and autoclave heating, respectively, under optimized conditions. The results indicate that maximum sugar yield depends upon delignification of biomass as lignin inhibits conversion of cellulose into sugars. It can be concluded that excellent delignifying capability of the H2O2-activated ammonium molybdate system can be achieved through microwave radiation.
