Bio Ethanol from Ligno cellulose Biomass


Mr. M. Kiran Kumar on 24th October 2014 at 11:30 am

With the short coming of fossil fuels in future, current research focus has been in alternate fuels such as solar, wind, biofuels etc which are renewable. Biofuels can be alternative to transportation fuels either by blendingor as lead fuel without any engine modification. Firstgeneration biofuels which are made from sugar, starch, or vegetable oil are not acceptable as fuel as it primarily debates overfood v/s fuel, hence; focus has been shifted to second generation and third generation biofuels. Bioethanol from lignocellulose biomass is second generation biofuels.Ligno-cellulose biomasses are generally agro-residues such as sugarcane trash, rice straw, wheat straw, cotton stalk etc... Lignocellulose biomass mainly consists of lignin, cellulose and hemicellulose. The cellulosic matter is separated from lignin and hemicellulose to an extent by pre-treating the biomass and this cellulosic matter is converted to sugars(hydrolysis) and these sugars are converted to ethanol (fermentation).
