| Abstract | In this study, waste shrimp shells from industry were used as a heterogeneous bio-based catalyst for trans-esterification reaction of fresh palm oil. CaO was prepared from shrimp shells calcination. Surface area, phase composition, and basicity of the calcined shrimp shell catalysts were studied using N2สadsorption (BET), X-ray diffraction (XRD), and CO2สtemperature-programmed-desorption (CO2-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. |
