Abstract

The increase in demand of power and the depletion of non-renewable sources call for an alternative source of energy. Biodiesel from microalgae is a potential alternative source of energy due to its high lipid content. However, the bulk of the energy requirement to produce biodiesel from microalgae is the drying process. Studies propose that microwave energy may be feasible for the drying process. Thus, this study is aimed to optimize the microwave drying process by means of a design of experiment. A full factorial of two factors each with three levels was selected for the design of experiment. The factors are the mass of the sample and power level of the microwave, and the response of interest was the drying efficiency. Statistical analysis revealed optimum factors setting and the dried biomass product produced under this condition was characterized by Fourier Transform Infrared Spectroscopy and the Gas Chromatograph - Flame Ionization Detector. © 2017 IEEE.
