Synthesising unsaturated fatty alcohols from fatty methyl esters using catalysts based on ruthenium and tin supported on alumina
Most promising catalysts for synthesising unsaturated fatty alcohols are based on group 8 metals with a promoter like tin, because the process can be carried out in moderate conditions, and these metals are less toxic than chromium. There have been no reports about the use of this catalyst to date...

| description |
Most promising catalysts for synthesising unsaturated fatty alcohols are based on group 8 metals with a promoter like tin, because the process can be carried out in moderate conditions, and these metals are less toxic than chromium. There have been no reports about the use of this catalyst to date using raw materials like methyl ester blends or evaluation reusing catalysts. This paper presents the hydrogenation of methyl esters from palm oil and commercial methyl oleate with Ru-Sn/Al2O3 catalysts prepared by impregnation, at moderate pressure and temperatur (5 MPa and 270°C). Greater selectivity to unsaturated alcohol and the less selectivity to methyl stearate was found for an optimal Sn:Ru=2 ratio. Hydrogenation of palm oil methyl esters with this catalyst produced a mixture of oleyl alcohol, saturated alcohols having 16-18 carbon atoms and heavy esters. Raw material had no great effect on catalyst activity. However, the catalyst showed deactivation through several uses due to decreased catalytic area. |

A la fecha no se han realizado estudios de estos catalizadores con materias primas como mezclas de metil-ésteres o evaluaciones de la reutilización de ellos. En este artículo se estudia la hidrogenación de metilésteres derivados del aceite de palma y de metiloleato comercial con catalizadores de Ru-Sn/Al2O3 preparados por impregnación, a presión y temperatura moderadas (5 Mpa y 270 °C). Se encuentra que para una relación óptima Sn/Ru = 2 se obtiene mayor selectividad hacia el alcohol insaturado y menos hacia metilestearato. La hidrogenación de metilésteres del aceite de palma con este catalizador da lugar a una mezcla de alcoholes insaturados y de saturados de 16 y 18 carbonos, además de ésteres pesados. El tipo de materia prima no tiene un efecto muy significativo sobre la actividad del catalizador; sin embargo, éste presenta desactivación a lo largo de varios ensayos debido a la pérdida de área catalítica.application/pdfspaUniversidad Nacional de Colombia - Facultad de Ingenieríahttp://revistas.unal.edu.co/index.php/ingeinv/article/view/20528Universidad Nacional de Colombia Revistas electrónicas UN Ingeniería e InvestigaciónIngeniería e InvestigaciónIngeniería e Investigación; Vol. 31, núm. 1 (2011); 74-82 Ingeniería e Investigación; Vol. 31, núm. 1 (2011); 74-82 2248-8723 0120-5609Echeverri, David Alexander and Rios, Luis Alberto and Marín, Juan Miguel (2011) Synthesising unsaturated fatty alcohols from fatty methyl esters using catalysts based on ruthenium and tin supported on alumina.
