Elaboración de un biocombustible a partir del aceite extraído de las semillas de moringa (Moringa oleífera)

Abstract

The objective of the present work of curricular integration called: "Elaboration of a biofuel from the oil extracted from Moringa oleifera seeds" consisted of the investigation and experimentation of the physical and chemical transformations and other technological processes that the moringa oleifera seeds underwent to obtain renewable energy. The development of the proposed work was considered as the first instance in the physicochemical characterization of moringa oleifera, where the process variables were constituted by 2.56% of fiber, 6.215% in pH, 76.89% of humidity and 1.45% in total nitrogen, continuing with the physical and chemical characterization of the biofuel, obtaining as a result 10ml of moringa oil, in the transesterification process, a solution of 0.30 g of (KOH) and 10.970 ml of CH3OH was used ,with 28.743 ml of moringa oil, at an agitation speed of 600 rpm, and a temperature of 65°C, resulting in biofuel, which was subsequently combined with allophane nanoparticles to improve the calorific value of the biofuel under ASTM D- 240 Standard, resulting in MJ/kg 39.68 MJ/kg, kinematic viscosity of 3. 78 mm2/s, flash point of 187.19°C, cetane index 51, yield 89.89% and API density of 29.046. Finally, in the development of the statistical analysis the null hypothesis was accepted where the concentrations of allophane nanoparticles do not affect the calorific value of the biofuel; therefore it is recommended to use cold pressing in order to obtain a greater volume of oil extraction and reduce costs.
