In this research, calcium methoxide was synthesized as solid base catalyst from quick lime for biodiesel production. The catalyst was further characterized by scanning electron microscopy (SEM), X-ray diffraction (XRD), attenuated total reflection fourier transform (ATR-FTIR) and Energy-dispersive X-ray spectroscopies (EDX) to evaluate its performance. The transesterification of refined palm oil using calcium methoxide and the process parameters affecting the fatty acid methyl ester (FAME) content such as catalyst concentration, methanol:oil molar ratio and reaction time were investigated. The results showed that the FAME content at 97% was achieved within 3 h using 3 %wt catalyst loading, 12:1 methanol:oil molar ratio and 65 °C reaction temperature. The result of FAME suggested calcium methoxide was the promising solid catalyst for substitution of the conventional liquid catalyst.

Palm Oil Biodiesel

Deep eutectic solvents (DESs) have numerous potential applications as cosolvents. In this study, use of DES as organic solvents for enzymatic biodiesel production from degumming palm oil (DPO) was investigated. Deep eutectic solvent was synthesized using choline chloride salt (ChCl) compounds with glycerol and 1,2-propanediol. Deep eutectic solvent was characterized by viscosity, density, pH and freezing values, which were tested for effectiveness by enzymatic reactions for the production of palm biodiesel with raw materials DPO. Deep eutectic solvent of ChCl and glycerol produced the highest biodiesel yield (98.98%); weight of DES was only 0.5 % of that of the oil. In addition, the use of DES maintained the activity and stability of novozym enzymes, which was assessed as the yield until the 6th usage, which was 95.07 % biodiesel yield compared with the yield without using DES. Hence, using DES, glycerol in enzymatic biodiesel production had high potentiality as an organic solvent for palm oil biodiesel production

Global Agenda

The continued using of petroleum energy as a sourced for fuel is widely recognized as unsustainable because of the decreasing of supplies while increasing of the demand. Therefore, it becomes a global agenda to develop a renewable, sustainable and alternative fuel to meets with all the demand. Thus, biodiesel seems to be one of the best choices. In Malaysia, the biodiesel used is from edible vegetable oil sources; palm oil. The uses of palm oil as biodiesel production source have been concern because of the competition with food materials. In this study, various types of biodiesel feedstock are being studied and compared with diesel. The purpose of this comparison is to obtain the optimum engine performance of these different types of biodiesel (edible, non-edible, waste cooking oil) on which are more suitable to be used as alternative fuel. The optimum engine performance effect can be obtains by considering the Brake Power (BP), Specific Fuel Consumption (SFC), Exhaust Gas Temperature (EGT) and Brake Thermal Efficiency (BTE).

Coal fly ash (CFA) and bottom ash (BA) obtained from coal fired power plants in Thailand and local supplier were characterized using XRF, XRD and N2 adsorption-desorption techniques. Their possibilities for conversion of palm oil into biodiesel were investigated. Selected CFA was also modified with lanthanum (La) at different La loading and the influence of La loading on biodiesel conversion was evaluated. The resulted showed that the Class C CFA as contained large amount of CaO (free lime) could catalyze the transesterification to achieve the highest FAME content of 89% under the operation conditions; the reaction temperature of 200 °C, the reaction pressure of 39 bars, the catalyst loading of 5 wt% of oil, the molar of oil to methanol of 1:30 and the stirring speed of 600 rpm for 5 h. The addition of La on the Class C CFA had a negative effect on conversion of palm oil. The FAME content decreased gradually from 89 to 62% with increasing La loading from 0 to 1 wt%.

Biodiesel Synthesis

The disadvantages of conventional biodiesel synthesis trigger the birth of new biodiesel synthesis methods using the DBD plasma reactor. The conventional methods with homogeneous and heterogeneous catalysts have significant constraints that the formation of glycerol compounds in large enough quantities that require considerable energy. The aim of present experiment is to design DBD non-thermal plasma reactor coaxial pipe type and to do its performance test in converting biodiesel The feed stock used are palm oil, ethanol, and argon gas as plasma carrier. Such a chemical reactor, this plasma reactor is also influenced by reaction kinetics and hydrodynamic factors. From this research, it can be seen that the optimum feed and gas flowrate being operated is 1.64 and 41.67 mL/s. The plasma reactor is used in the form of a quartz glass tube surrounded by a SS-314 spiral coil as an outer electrode. The applied operating conditions are 1 : 1 molar ratio of methanol/oil, ambient temperature of 28 - 30 °C, and pressure 1 bar. From this performance test, it is found that this plasma reactor can be used to synthesize biodiesel from palm oil and methanol without catalyst, no formation of soap, and minimal byproducts.

Abstract Fatty acid methyl esters (FAMEs) are sustainable biofuel that can alleviate high oil cost and environmental impacts of petroleum-based fuel. A modified 1,200 W high efficiency fruit blender was employed for continuous transesterification of various refined vegetable oils and waste cooking oil (WCO) using sodium hydroxide as a homogeneous catalyst. The following factors have been investigated on their effects on FAME yield: baffles, reaction volume, total reactant flow rate, methanol-oil molar ratio, catalyst concentration and reaction temperature. Results indicated that the optimal conditions were: 2,000 mL reaction volume, 50 mL/min total flow rate, 1% and 1.25% catalyst concentration for refined palm oil and WCO, respectively, 6:1 methanol-to-oil molar ratio and 62 - 63oC, obtaining yield efficiency over 96.5% FAME yield of 21.14 ´ 10-4 g.J-1 (for palm oil) and 19.39 ´ 10-4 g.J-1 (for WCO). All the properties of produced FAMEs meet the EN 14214 and ASTM D6751 standards. The modified household fruit blender could be a practical and low-cost alternative biodiesel production apparatus for continuous biodiesel production for small communities in remote areas.

Bagasse Biochar

In this study, the utilization of sugarcane bagasse biochar (SCBB) as a solid catalyst was investigated for biodiesel production from palm oil industry waste residue. The catalyst was synthesized by sulfonation of SCBB to attach sulfonate functional group. Several analyses such as Nitrogen Gas Sorption Analysis, acidity, Fourier Transform Infra-Red spectroscopy, and X-ray powder diffraction (XRD) were applied to determine the properties of SCBB catalyst. The SCBB catalysts were tested to esterify the palm oil industry waste residue which contains of Free Fatty Acids (FFAs). The SCBB catalyst activity test revealed that the variables including catalyst amount, methanol to PFAD mass ratio, and temperature influenced the FFAs conversion. The highest of FFAs of 86.1% was reached at reaction temperature of 65 °C with the PFAD to methanol mass ratio of 4:1, and catalyst amount of 5 wt.% PFAD. The E-R kinetic model as developed can be described the mechanism of esterification reaction
