CaO was prepared from shrimp shells calcination. Surface area, phase composition, and basicity of the calcined shrimp shell catalysts were studied using N<sub>2</sub> adsorption (BET), X-ray diffraction (XRD), and CO<sub>2</sub> temperature-programmed-desorption (CO<sub>2</sub>-TPD), respectively. The influence of shrimp shells calcination temperature and operation condition, methanol to palm oil ratio on trans-esterification reaction, were investigated. Five hours trans-esterification was carried out at 65℃ using different shrimp shell at four different calcination temperature: 700, 750, 800 and 850℃ with 9:1 methanol to palm oil ratio to determine the suitable calcined catalyst with the highest FAME yield. Methanol to palm oil ratios were varied from 6:1, 9:1, 12:1 and 15:1 with the selected catalyst. According to the results, the highest basic strength of mixed CaO and hydroxy-apatite phases were received by 800℃ calcined shrimp shell catalyst, with the highest FAME yield of 87.54% under the optimum condition reaction: 65℃ reaction temperature, 5 h reaction time, 9 wt% catalyst loading, and 9:1 methanol to palm oil ratio.</span></span></p>}, number={2}, journal={Journal of Metals, Materials and Minerals}, author={POONANAN, Assadaporn and PRUKPAIBOON, Anupat and DIM, Paul Egwuonw and TERMTANUN, Mutsee}, year={2021}, month={Jun.}, pages={78–83} }
