| Green house effect and ozone layer depletion due continuous environmental pollution from fossil fuel has speed up the quest for search of alternative energy fuel. In recent year, biofouls has attracted much attention as a reliable substitute to fossil fuel. The objective of this study was to evaluate and characterize biofuel produced from Egusi vegetable oil by applying standard method of transesterification. This study was carried out at Processing and Storage Engineering Departmental (PSED) laboratory of National Centre for Agricultural Mechanization (NCAM), Ilorin Kwara State, Nigeria. The results of the proximate characterization of the produced Egusi vegetable oil shows crude protein, crude fibre, ether extract, moisture content, ash content and... |

| Tranesterification reaction was carried out on raw Shea Butter Oil (SBO) and Palm Kernel Oil (PKO) to separate the ester from glycerol using ethanol in the presence of potassium hydroxide as catalyst. The properties of biodiesel (ethyl ester) obtained from varying proportions of diesel were experimentally determined and compared with that of conventional diesel. The fatty acid profile of the oil samples were determined using standard methods. Four blends (10, 20, 25 and 30%) of SBO and PKO by volume with diesel oil were produced and fuel properties determined include viscosity, relative density, specific gravity, flash, cloud and pour points. Mean values of the six fatty acids (palmitic, stearic, oleic, linoleic) obtained for shea butter and palm kernel... |

| Raw material costs are responsible for the greater percentage of biodiesel production cost. In this research chicken and guinea fowl wastes eggshell were used as feedstock for the producing heterogeneous catalyst for production of biodiesel. Proceeding their utilization, calcium oxide (CaO) was obtained by calcining the eggshells which contains calcium carbonate (CaCO3) in a muffle furnace at of 1000 for four hours. The solid oxide catalyst produced were then characterized by the Brunauer-Emmett-Teller (BET) and XRF methods. The activity of the produced catalyst in transesterification of calabash seed oil with methanol was assessed, and the properties of biodiesel obtained were evaluated. The various effect of reaction time, reaction temperature,... |

| Abstract This work presents the results of a supercritical transesterification process of soybean oil using methanol, performed in a laboratory high pressure semi-batch reactor. A full description of the equipment and a standard operating procedure are also provided. Since fossil fuels are not renewable, biofuels such biodiesel, have gained attention over the past decades. Biodiesel is the result of the transesterification of triacylglycerols in vegetable oils or animal fats and it works as an alternative fuel for compression-ignition engines. Methanol was chosen to perform the reaction, at molar ratios of 1:24 (oil: alcohol) and 0.1 (CO 2:methanol), temperature of 280 °C and pressure of 130 bar. In order to decrease the reaction time, CO2 in the... |

| Biodiesel consists of long-chain fatty acid esters, derived from renewable sources such as vegetable oils, and its utilization is associated to the substitution of the diesel oil in engines. Depending on the raw material, biodiesel can contain more or less unsaturated fatty acids in its composition, which are susceptible to oxidation reactions accelerated by exposition to oxygen and high temperatures, being able to change into polymerized compounds. The objective of this work was to determine the oxidative stability of biodiesel produced by ethanolysis of neutralized, refined, soybean frying oil waste, and partially hydrogenated soybean frying oil waste. The evaluation was conducted by means of the Rancimat® equipment, at temperatures of 100 and 105ºC,... |
