Production of Butanol (C4H9OH) from Switchgrass

Abstract

Switchgrass being lignocellulosic biomass is most abundant renewable resource suitable for the unlimited supply of biofuel. Ethanol (C2H6O) and butanol (C4H9OH) procured a prevailing place in the incomplete supplanting or mixing with gas. Butanol (C4H9OH) created through successful treatment that makes a desire for future energy. Acid hydrolysis above room temperature with proper mass transfer can help in dissociation of lignocellulosic fibres and enhances sugar yield. This work carried out explained the pre-treatment effects of acid hydrolysis on switchgrass using different concentrations and acid types and further fermentation of butanol (C4H9OH). The maximum amount of sugar (33.15 mg/ml) produced after the hydrolysis by HNO3 with 0.5 mol/ltr concentration. The maximum amount of butanol (2.32mg/ml) was found by hydrolyzing with 0.5 mol/ltr of HNO3 after the fermentation of hydrozylate.
