Diesel engines are widely used in almost all professions and cannot be dispensed with in the near future. Now the fossil fuels which are mainly used in diesel engines are depleting continually accompanied by increasing consumption and prices, there is the need to find alternative fuel to fulfil the worlds energy demand. Alternative fuels like biodiesel, are being used as effective alternative for diesel. The feasibility of biodiesel production from palm oil was investigated with respect to its fuel properties. Though biodiesel can replace diesel satisfactorily, problems related to fuel properties persist. In this study an oxygenated additive 1-butanol (BU) was blended with palm oil biodiesel (POME) in the ratios of 1%, 3%, 5% and 7% and tested for their properties improvement. These blends were tested for energy content and various fuel properties according to ASTM standards. Qualifying of the effect of additive on palm biodiesel fuel properties can serve the researchers who work on biodiesel fuels to indicate the fuel suitability for diesel engines according to fuel standards. Blends of BU in POME resulted in an improvement in acid value, viscosity, density and pour point with increasing content of BU in the blend. Further improvement in the pour point temperature of the palm oil methyl esters 1-butanol blends (B-BU) at 7°C can be achieved by adding 7% BU additive to POME, accompanied by 8.07% decrease in energy content of biodiesel.

This paper describes the properties of refined, bleached, deodorized palm oil (RBDPO) as having the potential to be used as insulating liquid. There are several important properties such as electrical breakdown, dielectric dissipation factor, specific gravity, flash point, viscosity and pour point of RBDPO that was measured and compared to commercial mineral oil which is largely in current use as insulating liquid in power transformers. Experimental results of the electrical properties revealed that the average breakdown voltage of the RBDPO sample, without the addition of water at room temperature, is 13.368 kV. The result also revealed that due to effect of water, the breakdown voltage is lower than that of commercial mineral oil (Hyrax). However, the flash point and the pour point of RBDPO is very high compared to mineral oil thus giving it advantageous possibility to be used safely as insulating liquid. The results showed that RBDPO is greatly influenced by water, causing the breakdown voltage to decrease and the dissipation factor to increase; this is attributable to the high amounts of dissolved water.

Esterification of fatty acids from palm oil waste (sludge oil) as biodiesel liquid base has been done by using alum [Al2(SO4)3.14H2O] catalyst. Some reaction variables like reaction time, catalyst quantity, and molar ratio of sample-reactant was applied for optimal reaction. Yield of 94.66% was obtained at reaction condition 65 °C, 5 h, sample-reactant ratio 1:20, and catalyst quantity 3% (w/w). GC-MS analysis request showed that composition of methyl esters biodiesel are methyl caproic (0.67%), methyl lauric (0.21%), methyl miristic (1.96%), methyl palmitic (49.52%), methyl oleic (41.51%), and methyl stearic (6.13%). Physical properties of synthesized product (viscosity, refraction index and density) are similar with those of commercial product.   Keywords: alum, biodiesel, esterification, sludge oil

The environmental issues caused by synthetic lubricant oils necessitate the need for an environment-friendly lubricant. In this study, a novel approach is proposed for developing an environment-friendly bio-lubricant by blending mustard oil, coconut oil and its methyl esters. Properties of the bio-lubricant are studied and compared with commercial ISO VG 32 oil. The best among various blends prepared are selected based on a decision matrix. The results revealed that this method helps in pour point depression and also in achieving excellent oxidative stability as compared to the base vegetable oil. The newly formulated oil has a pour point lower than that of commercial oil and is found to be highly biodegradable. The anti-wear characteristics of the oil are improved using boric acid, and the viscosity of the oil is improved using ethyl vinyl acetate for meeting the industrial standards. The newly formulated oil complies with industrial standards and can be used as biodegradable lubricant oil.

In this study, the catalytic activity of dolomite was evaluated for the transesterification of Colombian RBD palm oil with methanol, carried out in a batch reactor at 333,15K and 600rpm. The activated dolomites (calcined at 1073.15K for 2h) were characterized by scanning electron microscope (SEM), energy-dispersive X-ray spectroscopy (EDS), Fourier transform infrared spectroscopy (FTIR), Hammett indicators method, and quantification of the surface area, average pore size and average pore volume BET. The influence of reaction variables such as catalyst amount (%wt /wt) and methanol / palm oil molar ratio (mole/mole) was investigated. Under the suitable reaction conditions, the amount of calcined dolomite equal to 4% (wt /wt) based on the weight of oil, the methanol-oil molar ratio equal to 9:1, and the reaction time = 1h, the methyl ester content of 82.67% of fatty acid methyl esters (FAME) can be achieved.

Palm Biodiesel, which can be produced from transesterification palm oil with methanol, is an alternative fuel for diesel engines. It can be mixed with diesel fuels and used in diesel engines with no or slight modification. Therefore, in this study, commercially available diesel fuel was blended with biodiesel produced from transesterification of palm oil. The stability of the pure palm biodiesel (B100) was investigated over a storage time of 2, 4 and 6 months. The study assessed the corrosion rate of metals exposed to palm biodiesel. The kinematic viscosity, density and flash points of the blends increased with biodiesel amount in the fuel blend. However, pour point of the blends decreased as the amount of biodiesel in the blends is increased. Kinematic viscosity, pour point and flash point slightly increased with storage time. The average corrosion rate for copper is 0.5341 mpy, 0.2438 mpy for aluminium and 0.1802 mpy for mild steel.
