Application of Pyrolysis and Hydrothermal Liquefaction Process to Convert Bio-Fuel from Biomass

Abstract

Abstract Rapid increase in demand of fuels creates the challenge for scientific community. The fossil fuel resources are declining day by day. So, biomass derived fuel starts to feel an exquisite alternative option, by reason of it develop from residual cooking oil, animal fats, or vegetable oils, etc. In present work biomass is converted into bio-fuel by the process of pyrolysis and hydrothermal liquefaction. But if it is compared with fossil fuel some undesirable properties have been found such like high oxygen content high water content, high corrosiveness and high viscosity etc. Directly biofuels cannot be used in IC engine due to their unwanted content in the fuel. Therefore upgrading of bio-fuel is needed to improve its properties for liquid fuels by the pre-treatment process of biomass. The purpose of biomass pre-treatment is the degradation of cellulose phibrils, lowering their crystallization and polymerization levels, hemicelluloses separation and degradation of cellulose. However application to this bio-fuel have been needed to enhance its properties for CI engine fuel using blending for direct use in engine application.
