Biodiesel synthesis by TiO2-ZnO mixed oxide nanocatalyst catalyzed palm oil transesterification process

Mixed oxides of TiO2-ZnO and ZnO catalysts are successfully synthesized by glycerol-nitrate combustion route and used as an active and stable catalysts for the biodiesel production. TiO2-ZnO catalyst exhibiting good catalytic activities, a 92.2% of FAME conversion achieved in 5 h at 60 °C reaction temperatures with 6:1 methanol to oil molar ratio was observed at 200 mg catalyst loading. The TiO2-ZnO mixed oxide catalyst shows good catalytic performance over the ZnO catalyst, which could be a potential candidate for the large-scale biodiesel production.
