The use of the biodiesel B-20 especially in low temperature causes a blockage in the diesel vehicle fuel filter, which in turn causes the vehicle to strike. The blockage is caused by the deposition of monoglycerides (MG) agglomeration. These MG deposits reduce the flow properties of B-20. In this study, the Sorbitan Monooleate (SMO) surfactant was used in palm oil biodiesel (B-100) with 3 variations of alcohol, which are methanol, ethanol, and octanol. For each biodiesel with 0.4% MG content, the concentration of SMO surfactant was varied by 0.1-1% by volume of biodiesel. The molar ratio of surfactant/co-surfactants used is 1:1. Samples of biodiesel were stored at room temperature (±27°C). The effect of SMO and three variations of alcohol was analyzed using two flow properties parameters: Cloud Point (CP), Cold Filter Plugging Point (CFPP), and also supporting data, such as flashpoint and acid number. CP and CFPP were tested every week for a month’s observation. The addition of SMO and octanol to palm oil biodiesel gave the best results by reducing CP by 4.4°C and CFPP by 3°C. The interaction between MG, oleic tails, and hydrogen bonding between them has been analyzed by Fourier-Transform Infrared Spectroscopy (FTIR) method. There are indications of intermolecular hydrogen bonding to MG after the addition of SMO and octanol at wavenumbers 3231.11 and 3289 cm-1.

Abstract The factors that influence microwave-assisted biodiesel production reactions have been analyzed in this investigation. The studied parameters included microwave (MW) power, irradiation time, and reactor pressure. The response surface method was used to optimize the reaction conditions. The conversion for the 6:1 methanol/oil molar ratio and 1% catalyst ranged from 68.4% to 96.71%. The optimized conditions were found to be 138 s of MW irradiation at 780 W and 7 bar pressure. The conversion at this point was 97.82%. Biodiesel yield increased at higher radiation times (90–130 s) and pressures (5–7 bar). Results show that MW power and irradiation time have significant effects at the 1% level, whereas pressure had significant effects at the 5% level on biodiesel production in this range. The major properties of the palm oil biodiesel produced herein have met the requirements of the EN 14214 methyl ester standard.

The effect of using B20 palm oil biodiesel on rail locomotive fuel filters was evaluated in this study. The generator water separator filter, generator main filter and locomotive drive filter after being used along the filter replacement period were analyzed in laboratories and compared with new ones as reference. The analysis was using SEM/EDS, FTIR and GC. The FTIR and GC test results show that the fuel filter has a number of deposits from the components of biodiesel fuel, that are diesel and biodiesel. However, morphological test results using SEM show that the filter surface has not been completely covered by liquid and fuel deposits. The results of the tests and analysis indicated that the usage of 125 hours (for locomotive genset) and 3 months for locomotive drive engine with 20% palm biodiesel fuel can still guarantee the filtration to maintain the performance and prevent damage to fuel and engine system components.

Biodiesel from palm oil is one of the alternative energies developed in Indonesia and has been implemented since 2018 for marine transportation, especially for ships. However, there are pertinent cases that experienced many obstacles related to the occurrence of gels, engine power reduction, blocking filters, and injection in the engine. The occurrence of those cases is due to the prolonged storage of biodiesel onboard of ships. During a significant storage process, periodic biodiesel monitoring is required which is difficult to do onboard. In this paper, a study on the physical/chemical characteristics of biodiesel and microbiological growth had been carried out in a controlled effect of the marine environment. Samples of biodiesel blends B20 were placed in locations near the sea and land base areas. It was found that there were significant changes in some chemical parameters of the biodiesel, such as flash point, viscosity, and acid number after 30 days. Microbiological growth, specifically bacteria, appeared on the 45th day of the outdoor-land sample. On the other hand, fungus growth on the out-door-sea was also detected on the same day. It suggested that the growth of microorganisms, growth of fungus and change in characteristics of the marine environment causes the degradation of biodiesel.

The purpose of this paper was to analyze palm oil biodiesel production under different conditions and to verify the relationships between production variables in order to optimize biofuel production using response surface methodology (RSM). Biodiesel was produced through transesterification process by methyl route and alkali catalyst (NaOH) 1% (m/m). The analyzed variables were: four molar ratios (3:1, 4:1, 6:1 and 8:1); three temperature reactions (45°, 52° and 60°C); and three time reactions (40, 60 and 80 minutes). For the palm oil biodiesel production, the highest yield was 93%, obtained via a molar rate of 3:1, 52°C and 60 minutes. This result differs from previous studies that found a higher yield with molar ratio increases, implying greater expenses of methanol. Kinetic viscosity and specific mass were also analyzed, and the values are within the Brazilian, American, and European standards. The results showed that the most influent factor in biodiesel production was the molar rate. In relation to the biodiesel characterization, using the RMN H1 technique, it was possible to obtain the transesterification reaction yield of 79.50% for the 3:1 palm oil biodiesel. Through gas chromatography, it can be verified that the predominant fatty acids in the samples were palmitic and oleic acids.

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.
