Biodiesel Production from Canola Oil Using TiO2CaO as a Heterogenous Catalyst

Biodiesel is one of the renewable energy sources that an alternative to fossil diesel non-toxic and produces less CO emissions. Transesterification process a conventional mechanism produce biodiesel from vegetable oil with homogeneous or heterogenous catalyst. However, catalysts are considered as more efficient than homogenous catalysts. Recently, TiO2/CaO has been used compound catalyst palm oil, waste cooking oils algae. In this research, was manufactured using canola feedstock titanium dioxide / calcium oxide (TiO2/CaO) The aim study prepare catalyst, investigate transesterification measure chemical physical properties. Catalyst preparation required four stages: dry mixing, wet water separation activation where there were two temperature phases (200 °C 600 °C). mixed methanol by 1:16 ratio had different mixing time (30 minutes, 60 90 minutes). blending catalyst-methanol mixture under 3 (4 hours, 5 6 hours). characterization analysis X-ray Diffraction (XRD), Scanning Electron Microscopy (SEM), effects effects. showed optimization conditions temperature, minutes 1.5% wt. concentration hours time. yield 96.9%. Moreover, new parameters applied for research (time conditions). properties (kinematic viscosity, flash point content) measured according ASTM D6751 standards similarity 98%. Therefore, can be produced TiO2/CaO, but still needs studies on several topics such multi feedstocks, ethanol impact poisoning in case TiO2-CaO
