Heterogeneous Acid Catalyst

The aim of this research was to synthesize, characterize, and apply a heterogeneous acid catalyst to optimum biodiesel production from hydrolyzed waste cooking oil via an esterification reaction, to meet society’s future demands. The solid acid catalyst S–TiO2/SBA-15 was synthesized by a direct wet impregnation method. The prepared catalyst was evaluated using analytical techniques, X-ray diffraction (XRD), Scanning electron microscopy (SEM) and the Brunauer–Emmett–Teller (BET) method. The statistical analysis of variance (ANOVA) was studied to validate the experimental results. The catalytic effect on biodiesel production was examined by varying the parameters as follows: temperatures of 160 to 220 °C, 20–35 min reaction time, methanol-to-oil mole ratio between 5:1 and 20:1, and catalyst loading of 0.5%–1.25%. The maximum biodiesel yield was 94.96 ± 0.12% obtained under the optimum reaction conditions of 200 °C, 30 min, and 1:15 oil to methanol molar ratio with 1.0% catalyst loading. The catalyst was reused successfully three times with 90% efficiency without regeneration. The fuel properties of the produced biodiesel were found to be within the limits set by the specifications of the biodiesel standard. This solid acid catalytic method can replace the conventional homogeneous catalyzed transesterification of waste cooking oil for biodiesel production.

A new ketal cyclic from ethyl 9,10-dihydroxyoctadecanoate with acetone had been synthesized by reflux and sonochemical method. The synthesis was performed via several steps of reaction, i.e.: transesterification, hydrolysis, oxidation with 1% KMnO4 in basic condition, esterification, and ketalization. The structures of the products were confirmed by FTIR, GC-MS, 1H- and 13C-NMR spectrometers. Direct transesterification of used cooking oil produced a mixture of ethyl ester in 82.94% yield meanwhile hydrolysis of this mixture gave free fatty acids mixture in 88.46% yield. Hydroxylation reaction of free fatty acids mixture yielded a white powder of 9,10-dihydroxyoctadecanoic acid in 46.52% yield. Esterification of 9,10-dihydroxyoctadecanoic acid and ethanol catalyzed by sulfuric acid with reflux condition for 4 hours and sonochemical method, respectively yielded 90% and 93.8% of ethyl 9,10-dihydroxystearate. In the other side, the utilization of KSF montmorillonite as catalyst conducted with reflux gave 52% in yield of ester. Furthermore, the use of acetone in 45 minutes sonochemical method with montmorillonite KSF catalyst gave cyclic ketal (ethyl 8-(2,2-dimethyl-5-octyl-1,3-dioxolan-4-yl)octanoate) as a yellow viscous liquid in 53.30% yield. From physicochemical properties –density, kinematic viscosity, viscosity index, total acid number, total base number and iodine value- gave the conclusion that this novel compound is potential biolubricant candidates to be developed.

This work has investigated the reusability of silica-titania in various temperatures (50 – 70°C) of biodiesel production from waste cooking oil. The reused silica-titania catalyst collected from silica-titania catalyst waste produced from the process of separating the catalyst from biodiesel products from palm oil and used cooking oil at various temperatures. The 1st and 2nd reused SiO2-TiO2 were characterized by DR UV-Vis and the spectra were deconvoluted for calculate the fraction of titanium in tetrahedral coordination. In addition the biodiesel products were characterized using FTIR, and several properties of biodiesel such as density, flow rate and acid value were analyzed in order to get the information about catalytic activity reused SiO2-TiO2. The results show the titanium tetrahedral fraction in reused catalyst (1st) and (2nd) are found to be 24,98% and 24.65%, respectively. The FTIR characterization of biodiesel products and waste cooking oil are almost similar. The analysis of waste cooking oil converted to biodiesel shows an optimum temperature of 50oC that at this temperature the lowest density or highest flow rate gave highest conversion of 47.82% using BCR1 and 39.13% using BCR2.
