Bio-oil production from microalgae through lignite assisted microwave pyrolysis as novel absorber
Description
Bio-oil from microalgae has undergone changes from the first generation to the third generation. Microalgae are third-generation bio-oil producers which have advantages over other bio-oils. This study aims to determine the yield and quality of bio-oil from microalgae through microwave pyrolysis with lignite as an absorber. The microalgae used are Chlorella vulgaris and lignite can be used as an absorber and can contribute to increasing the thermal decomposition results. Microwave pyrolysis was operated under vacuum (-10 mmH2O) and the process temperature was 500 °C. Process variables that directly contribute to the increase in yield and quality of bio-oil include the ratio of lignite to microalgae, pyrolysis time, and microwave input power. The resulting bio-oil product will be characterized by FTIR, GC-MS, density and viscosity. The ratio of microagla to coal which gives a maximum yield is 4:6 with an input power of 450 watts and a reaction time of 60 minutes which gives an optimal yield of 40%. The results of this study are expected to provide an alternative use of bio-oil and lignite as an absorber.
