Comparison of Cr/C and Cr2O3/Z Catalysts on Hydrocracking of Bio Oil from Pyrolysis of Palm Empty Fruit Bunches

Bio-oil derived from palm empty fruit bunch is not suitable for fuel purpose due to high acidity and low heating. Cr2O3/Zeolite and Cr/C catalysts was developed to upgrade bio-oil through hydrocracking. The catalyst prepared via impregnation method followed by oxidation-reduction. Ammonia and pyridi...
