espanolSe estudio la hidrogenacion de aceite crudo de Jatropha usando dos catalizadores comerciales 3 niquel/silice y niquel/alumina. Se realizo un diseno experimental 2 , comprendiendo las variables temperatura, presion y contenido de catalizador. El aceite y sus productos de reaccion fueron caracterizados mediante la medicion de composicion y los indices de acidez, saponificacion y yodo. Los catalizadores se caracterizaron por area BET, FT-IR, TPR y TGA. Dentro de los resultados mas relevantes del presente trabajo estan: a) el catalizador niquel/silice mostro mayor actividad, debido posiblemente a su mayor area superficial, lo cual pudo favorecer la dispersion del niquel; b) se encontro una alta estabilidad a la oxidacion del catalizador niquel/silice, lo que le confiere un alto grado de reutilizacion; c) se obtuvo un producto con una hidrogenacion mayor al 98% con potenciales aplicaciones en lubricantes textiles, aditivos suavizantes, entre otros. EnglishHydrogenation of crude Jatropha oil using two commercial catalysts nickel/silica and nickel/alumina was studied. An experimental design 23 was carried out, including the variables temperature, pressure and content of catalyst. Oil and their reaction products were characterized by measuring composition and acid value, saponification and iodine. The catalysts were characterized by BET area, FT-IR, TPR and TGA. Among the most relevant results are: a) The catalyst nickel/silica showed higher activity, possibly due to its larger surface area, which could favor the dispersion of nickel; b) high stability to oxidation by catalyst nickel/silica was found, which gives a high degree of reuse; c) a product with hydrogenation greater than 98% with the potential to apply in textile lubricants, softening additives, among others.
