Abstract

Zirconium dioxide catalyst was prepared from ZrOCl2·8H2O by sol-gel method using ammonium hydroxide as hydrolyzing agent and calcined at 500 °C for 5 h. The catalyst basicity was analyzed by Hammet-indicator method and its thermal stability, crystalline phase, surface morphology, surface area, porosity characterizations were obtained respectively by TGA, XRD, SEM and BET techniques. The yield of 90.9 % was achieved under the optimal conditions; 20 wt % catalyst, time 10 h, methanol:oil molar ratio, 1:18 at temperature 70 °C at high stirring rate of 1400 (± 20) rpm. The application of commercial ZrO2 was also tested under optimal conditions and got a yield of 19.4. The biodiesel properties of Garcenia gummi gutta (L. Robson) oil were evaluated as per the Bureau of Indian Standards and the oil was found to be a novel biodiesel feedstock.
