Fatty acid methyl esters (biodiesel), prepared from transesterification of vegetable oils or animal fats, have gained great importance in substituting petroleum based diesel for combating environmental problems and higher diesel prices. Moringa oleifera fatty acids are among the newly investigated potentials for biodiesel production in recent years. In getting rid of soap formation and thus large waste washing water from biodiesel produced from homogenous catalysts, the use of heterogeneous catalysts is currently preferred due to easily separation and purification of the final products. In this study, biodiesel was produced from moringa oleifera oil using sulfated tin oxide enhanced with SiO2 (SO42−/SnO2−SiO2) as super acid solid catalyst. The experimental design was done using design of experiment (DoE), specifically, response surface methodology based on three-variable central composite design (CCD) with alpha (α) = 2. The reaction parameters in the optimization process were reaction temperature (60°C to 180°C), reaction period (1 to 3 hrs) and methanol to oil ratio (1:6 to 1:24 mol/mol). It was observed that the yield up to 84wt% of moringa oleifera methyl esters can be obtained with reaction conditions of 150°C temperature, 150 minutes reaction time and 1:19.5 methanol to oil ratio, while catalyst concentration and agitation speed are kept at 3wt% and 350 rpm respectively.

Background: Since time immemorial, humans have always been interested in lipids for various uses, namely food, cosmetology, medicine, etc. Many seeds, sources of oils, are increasingly studied for their nutritional and therapeutic properties. Methods: The present study aims to valorize the vegetable oil obtained from the seeds of the Moringa oleifera plant widely cultivated in the southwest of Algeria, using the solid-liquid extraction technique. In addition, the fatty acid analysis of this oil, using the gas chromatography technique. Result: An oil yield of 30.43% was obtained, revealed that it contains ten different compounds. The characterization of the oil obtained (physico-chemical properties such as organoleptic properties, density, viscosity, refractive index) proved to comply with international standards and AFNOR standards. In addition, it turned out that Moringa oleifera oil has a very interesting antioxidant power. However, this oil did not show any antibacterial activity on the strains tested.
