Abstract

DEL RIO, Juan I; CARDENO, Fernando; RIOS, Luis A  and  PENA, Juan D. Hydrogenation of Crude Jatropha Oil for Industrial Applications. Inf. tecnol. [online]. 2015, vol.26, n.6, pp.03-12. ISSN 0718-0764.  http://dx.doi.org/10.4067/S0718-07642015000600002.

Hydrogenation 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.

Keywords : hydrogenation; nickel catalyst; Jatropha crude oil; temperature reduction; experimental design.
