Supercritical Fluid Treatment for the Production of Biofuels From Microalgae

Abstract

Fast-growing microalgae have the potential to become an alternative and sustainable feedstock for biofuel production. Cultivated microalgae were treated with the supercritical mixture of ethanol and carbon dioxide in order to increase the production of biodiesel and ethanol. Optimum conditions for the simultaneous reactions involving algal oil transesterification and cellulose hydrolysis/fermentation were investigated. The experiments were carried out to study the effect of reaction time, temperature (250-400 °C), reaction pressure (10-40 MPa), and molar ratio (5-45) of alcohol to triglycerides on the biodiesel formation and saccharification yield. Analyses of oil, carbohydrate, biodiesel, ethanol, and by-products obtained from different processing conditions were carried out to ascertain the efficiency.
