PRODUCTION OF BIO-GASOLINE FROM CATALYTIC PYROLYSIS OF CANDLENUT OIL BIODIESEL (Aleurites moluccana) AND POLYSTYRENE WASTE MIXTURE

Abstract

The production of bio-gasoline from candlenut oil biodiesel (Aleurites moluccana) and polystyrene waste mixture has been successfully carried out through the catalytic pyrolysis process. Al-MCM-41: ceramics (7:3) is used as the catalyst in the pyrolysis process at the reaction temperature of 300°C. This study evaluated the effect of feedstock ratios on the gasoline fraction (C7 – C12) and the physical properties of the fuel blend. The chromatogram of GC-MS analysis confirmed that the bio-gasoline obtained from the feedstock ratio of 1:1 gives the highest gasoline fraction (81.17%). Moreover, the result of the physiochemical analysis showed that the fuel blend from the feedstock ratio of 1:1 has a high calorific value (16.663 kcal/kg) and octane number (100.5).
