Production Biofuels from Palm Empty Fruit Bunch by Catalytic Pyrolysis Using Calcined Dolomite

In this study, Palm Empty Fruit Bunch (PEFB) was utilized to produce bio-oil through non-catalytic and catalytic pyrolysis process. A fixed-bed reactor was applied to conduct pyrolysis experiments at atmospheric pressure. Comparison of bio-oils obtained from non-catalytic and catalytic pyrolysis wih different pyrolysis temperature was studied in terms product yield. The maximum bio-oil yield of 52.4% was obtained at pyrolysis temperature of 600 °C. Furthermore, based on Gas Chromatography-Mass Spectrophotoscopy (GC-MS) analysis, the percentage of phenolic compounds in bio-oil products from catalyzed pyrolysis showed more higher compared with the non-catalyzed pyrolysis.
