Optimization of Operational Parameters for Production of Bio-ethanol from Red Gram Straw
Abstract: AbstractBio-alcohol is a neat and cleaner source of energy, which could be obtained from locally available biomass. However, the complex structure of lignocellulose in biomass makes a primary protective barrier that prevents cell destruction. In order to break down this structure for the conversion of biomass to fuel ethanol, the cellulose and hemicellulosic materials must be broken down to corresponding monomers (sugars). It could be done easily with acid hydrolysis …
