In this study, the biodiesel production of waste cooking oil using calcium methoxide as solid base catalyst was investigated. The calcium methoxide catalyst was synthesized from calcined quick lime reacted with methanol. The XRD result showed that the catalyst was successfully synthesized with sufficient purity. The strength of catalyst was examined on the transesterification reaction of waste cooking oil and methanol. Parameters affecting on transesterification such as the catalyst concentration, methanol-to-oil-molar ratio, reaction time and reaction temperature were investigated. The results showed that the percentage of fatty acid methyl ester conversion of 99.06%. The optimum conditions were achieved within 3 h using 3wt% catalyst concentration, 12:1 methanol-to-oil molar ratio and 65°C reaction temperature. In addition, the kinetic study of transesterification reaction was carried out at the temperature from 30°C to 65°C. The pseudo-first order was good agreement with the experiment results. The reaction rate constant (k) and activated energy (Ea) were determined as 0.023 min-1 and 55.77 kJ/mol, respectively.

Waste cooking oil has a high potential as a raw material in biodiesel production due to its abundant availability and cheapest among other feedstock. Hence transesterification reaction is carried out using waste cooking oil in this research. The objective of this study is to synthesize and characterize the catalyst. On the other hand, deoiled spent bleaching clay impregnated with 40% CaO utilized as a catalyst. Optimization was carried out on methanol to oil molar ratio (6:1-24:1), catalyst loading (3-10 wt.%) and reaction duration (2-10 h). The catalyst of deoiled spent bleaching clay doped with 40% CaO was prepared by wet impregnation method and calcined at 500 °C for 4 hours. The catalyst shows high activity under optimum condition of 5 hours of reaction time, 12:1 of methanol to oil molar ratio with 7 wt.% of catalyst. The transesterification yields 84.7% methyl ester. Therefore, this catalyst has potential to be used in the transesterification of waste cooking oil in producing biodiesel due to its high activity. Copyright © 2016 BCREC GROUP.

In our work, biodiesel was prepared from Tra fat by methanolysis reaction using activated calcium oxide as solid base catalyst. Effects of various process parameters on biodiesel production such as molar ratio of methanol to fat, catalyst concentration, temperature and time of reaction and the active mechanism of CaO catalyst for the transesterification reaction were investigated. The results show that CaO has strong basicity and high catalytic activity as a heterogeneous solid base catalyst and the transesterification reaction takes place on basic sites of calcium diglyceroxide formed due to the reaction between Cao and the by-produced glycerol. The biodiesel yield achieves 92.95 % at 60°C, 90 minutes, 8:1 molar ratio of fat to methanol, and 6 % CaO catalyst. Important fuel properties of the produced biodiesel meet the specifications of ASTM D 6751 biodiesel standard.
