Biofuel Production from Jatropha Bio-Oil Derived Fast Pyrolysis: Effect of Catalysts Supported

Abstract:

This research focus on catalytic hydrotreating of Jatropha Bio-oil derived fast pyrolysis into biofuel was investigated to determine the effects of the supported type (Al₂O₃ TiO₂ and Al₂O₃-TiO₂ mix-oxide) and of the variables temperature (300-340 °C). The synthesized catalysts were prepared by sol-gel method for support and wet-impregnation with solution promoter on support, and characterization by BET NH₃-TPD XRD and NO-TPD for active site analysis of catalysts. The reaction was carried out in a Parr batch reactor under H₂ atmosphere about 50 bar for 2 h. The catalytic activity was evaluated for % fatty acid conversion (%FFA), %HDO, %selective to paraffin/olefin products. The results showed that the CMA gave the %FFA is highest, but low selective products, then the CMT gave the % HDO high than CMA, while the mixed-oxide were proving the %HDO, %FFA conversion and % selective is increasing because the TiO₂ incorporated with Al₂O₃ effect to increase the amount of rim site, it’s active site for HYD partway.
