Abstract

The rapid increasing of fuel consumption cause the resource is depleting fast and threat the continuation of energy supply. That is the reason why petroleum price is rising. Therefore, the variation of alternative fuels are being exploited to sustain the energy requirements in the future. Recently, there is no technology to utilize glycerol from transesterification process in Indonesia. However, glycerol could be utilized into fuel as bio-oil by pyrolysis. Pyrolysis is thermal decomposition occuring in the absence of oxygen and produce of brown liquid that contained oxygenated compounds, called bio-oil. Catalytic and non-catalytic pyrolysis was run at temperatures of 400 0C, 500 0C, 600 0C and at flow rates of 300 mL/s, 400 mL/s, and 500 mL/s. Glycerol as feed was vaporized and brought by the carrier gas. For the catalytic pyrolysis, 10 g fresh Grace DavisonĀ® pellet catalyst was used for each run. The flue vapor is passed into condenser to get the liquid fraction, bio-oil. The research obtained the liquid fraction yield, thermal stability, and also the best calorific value. The best liquid fraction yield was obtained at 600 0C and 500 mL/s for non-catalytic process. Bio-oil from catalytic pyrolysis is more stable than the other one. However, the best calorific value of bio-oil from non-catalytic process was 18645 J/g and 17149 J/g for bio oil from catalytic process.
