The interest on renewable energies including biomass has been intensified worldwide due to depletion of fosil fuels and environmental concerns in the last decade. The use of both lignocellulosic and algal biomass is widely investigated because of their low cost and high availability. In the present study, catalytic pyrolysis of Pavlova microalgae was performed over titania based catalysts in a fixed bed reactor at various temperatures. The effects of catalysts on product yields and character were investigated. There was a clear effect of the catalysts on the product yields and quality, which were able to recover a large fraction of the starting microalgae energy (∼66-76 %) in the bio-oils. Bio-oil yield was found to be highest in presence of Fe/TiO2 (24.34 wt.%) and the lowest in presence of Mg/TiO2 (21.68 wt.%) in the catalytic runs. The higher heating values (HHVs) of produced bio-oils were in the range of ∼31-34 MJ/kg and suffered strong deoxygenation, with oxygen content (% daf) decreased from 52.29 wt.% in the starting microalgae to ∼14-17 wt.%. The oxygen contents in the bio-oils were relatively lower than those previously obtained using ZSM-5 (25 wt.%) and other species without catalyst (17-24 wt.%). Also, catalysts were able to reduce the nitrogen content by ∼29-38 wt.% in the bio-oil obtained without catalyst. 1H NMR analysis proved that catalysts have increased the total aliphatics and decreased the oxygen-containing compounds in the bio-oils compared to without catalyst. GC-MS analysis showed that the bio-oils were enriched in aliphatic units and depleted in oxygenates.
