This study focuses on a feasibility study of alternative nonedible crude oil such as jatropha and used cooking oil in biodiesel production. Crude jatropha oil (CJO) and used cooking oil (UCO) were converted to biodiesel using a two-step transesterification process with presents of acid-based and alkaline-based catalysts. Each three biodiesel blends (B5, B15 and B25) have been produced by blended with conventional diesel fuel (CDF). Determination of the fuel properties for each blend including CDF, Jatropha Methyl Ester (JME) and Used Cooking Oil Methyl Ester (UCOME) have been carried out. The average yield for jatropha and used cooking oil biodiesels production was 94.3% and 92% respectively. The increment of the percentage of JME or UCOME in its blends is proportional to fuels physical properties such as density, specific gravity, kinematic viscosity and surface tension, however inversely proportional to fuels calorific value. Based on the results of this study, it is acceptable to conclude that non-edible CJO and UCO are viable alternatives to edible oil as feedstock to renewable fuel in order to reduce the greenhouse gases produced.

Transesterification of waste cooking oil using CaO/MCM-41 synthesized from Lapindo mud by the sonochemical method has been carried out. The silica was separated from the mud by reflux method used 6 M HCl and 6 M NaOH. The silica was then analyzed by XRF and used as silica source in MCM-41 synthesis. The synthesis of MCM-41 was carried out by the sonochemical method, then analyzed by XRD, Infrared spectrophotometer, SAA, and TEM. The Ca2+ was loaded onto the MCM-41 by wet impregnation method under variation of the Ca2+ content of 1.15, 1.29, 2.39, and 3.25 wt.% analyzed by ICP produced CaO(1), CaO(2), CaO(3), and CaO(4)/MCM-41 catalyst respectively. Transesterification of used cooking oil was carried out under methanol/oil mole ratio of 15/1, the temperature of 55, 65 and 75 °C, and catalyst/oil weight ratio of 5/100, 10/100 and 15/100 for 2 h by reflux method. The XRD analysis of the MCM-41 showed a characteristic peak at 2θ = 2-5°. The MCM-41 has a specific surface area of 1290 m2/g and pore diameter of 3.4 nm. The TEM images of MCM-41 showed ordered pore distribution with a hexagonal shape. The highest conversion of methyl ester was 78.17 wt.% obtained under the reaction conditions at 65 °C and catalyst/oil weight ratio of 15/100 using the CaO(4)/MCM-41. The lifetime CaO(4)/MCM-41 catalyst was 9.8 h.

The MCM-41 was synthesized using CTAB as a template by sonochemical method and it was charactherized by FTIR, XRD, SAA, and TEM. Potasium was impregnated onto the MCM-41 using potasium acetate salt solution with K+ concentrations of 0.80, 1.35, 1.86, and 2.49 wt.% to produce K2O(1), K2O(2), K2O(3), and K2O(4)/MCM-41 catalysts. The K2O/MCM-41 catalysts were then analyzed by ICP and SAA. Acitivity of catalysts were evaluated in the transesterification reaction of used cooking oil at 50, 60, and 70°C for 120 min. The MCM-41 showed characteristic peaks of 2θ = 2-3°C. The TEM images showed ordered pore distribution with a hexagonal shape. The MCM-41 and K2O(4)/MCM-41 have spesific surface area of 1282.33 and 225.81 m2/g with pore diameter of 30.49 and 30.12 Å, respectively. The highest conversion of methyl ester was obtained from transesterification at 70°C using K2O(4)/MCM-41 catalyst and it was about 79.80 wt.%. Catalyst lifetime of the K2O(4)/MCM-41 for transesterification of used cooking oil was about 15.41 h.
