| dc.description.abstract | En este trabajo se evaluó el efecto del método de preparación (auto-combustión Vs. impregnación) del rutenio como promotor (0,3 % Ru) de catalizadores a base de cobalto (10 % Co) soportado sobre óxidos mixtos de MgO-Al2O3 en la síntesis de Fischer-Tropsch (SFT). Los catalizadores soportados sobre MgO y Al2O3se utilizaron como materiales de referencia. En todos los casos, la actividad catalítica se evaluó en la SFTen un reactor de lecho fijo a 260 °C y presión atmosférica. De acuerdo a los resultados independientes del método de preparación empleado, los catalizadores soportados sobre óxidos mixtos favorecieron más los hidrocarburos más pesados (fracción C5+) que los materiales de referencia. En cuanto a los sistemas promovidos con Ru, se observó un incremento en la conversión de CO para los catalizadores preparados por autocombustión y una propensión hacia la formación de fracciones en el rango de la gasolina (C5 – C11) y del diésel (C12 – C21). En general, los resultados obtenidos indican que los sistemas catalíticos del tipo Ru-CoO/ Al2O3-MgO son promisorios para la síntesis F-T. | spa |
| dc.description.abstract | In this work we evaluated the effect of the preparation method (auto-combustion vs impregnation), and of ruthenium as promoter (0.3 wt% Ru) for cobalt-based catalysts (10 wt% Co) supported on MgO-Al2O3 mixed oxides on the Fischer-Tropsch synthesis (FTS). Cobalt supported on MgO and Al2O3were used as reference catalysts for the mixed oxides. The activity of the catalysts for the FTS was evaluated in a fixed-bed reactor at 260°C and atmospheric pressure. According to the results and independently from the preparation method,cobalt supported on MgO-Al2O3 mixed oxides were more selective to heavy hydrocarbons (C5+) than catalysts supported on single (MgO or Al2O3) oxides. Furthermore, all Ru-promoted catalysts were more active (i.e., had higher conversion) than non-promoted catalysts, and the selectivity to hydrocarbon fractions in the range of gasoline (C5 – C11) and diesel (C12 – C21) increased. In general, the results suggest that Ru-promoted Co/MgO-Al2O3 catalyst is a promising catalytic system for the FTS. | eng |
