Abstract

The renewable hydrocarbon-like biofuel from biomass is crucial to substitute fossil fuel. A series of mesoporous Al₂O₃-TiO₂ mixed oxide catalysts with different TiO₂ content (0.1Ti-0.9Al, 0.2Ti-0.8Al and 0.3Ti-0.7Al) have been synthesized. The physicochemical properties of the catalysts were characterized by XRD, FESEM-EDX, BET, FTIR, NH₃-TPD, FTIR-Py, and TGA. The deoxygenation (DO) of triglyceride (i.e. triolein) was carried out in the absence of hydrogen and solvent. The mesoporous Al₂O₃-TiO₂ catalysts showed high catalytic activity performance as compared to that of Al₂O₃ and TiO₂. It was found that 0.2Ti-0.8Al catalyst exhibited the highest conversion (76.86%), and selectivity (27.26%) toward n-C₁₅ + n-C₁₇ at 380 °C after 4 h. The excellence performance of mesoporous Al₂O₃-TiO₂ was attributed to its acidity, mesoporosity and larger surface area. The results reveal that the mesoporous Al₂O₃-TiO₂ catalyst is a promising catalyst for the synthesis of hydrocarbon-like biofuel.
