Investigation of palm fibre pyrolysis over acidic catalyst for bio-fuel production

This research aimed to evaluate the pyrolysis reaction for bio-fuel production from palm fibre. A preliminary step to investigate the effect of different type of heterogeneous catalyst revealed three different catalysts: zeolite type (H-Beta), tungsten–zirconia (WO3/ZrO2) and modified alumina (KOH/A...

A preliminary step to investigate the effect of different type of heterogeneous catalyst revealed three different catalysts: zeolite type (H-Beta), tungsten–zirconia (WO3/ZrO2) and modified alumina (KOH/Al3O2). An increase in temperature was found to have a positive impact on the production of bio-fuel. Bio-fuel synthesis performed in a stainless steel tubular reactor was found to optimized at 650 °C using WO3/ZrO2 as a catalyst resulting in 40.5% bio-fuel, 7.1% bio-char and 14.3% gas. Formation of gas product is due to the presence of strong acid sites on the surface of WO3/ZrO2 promoting cracking reactions.
