La2O3/CaO CATALYSTS AND ITS APPLICATION IN THE OXIDATIVE COUPLING OF METHANE
Descripción del Articulo
La2O3/CaO catalysts were prepared at different weight percentages of La2O3.Por the coprecipitation method described porRaO, CaCO3 is prepared and then it was impregnated in a solution of La (NO) 3.6H2O thus obtaining the catalyst precursor . precursors dried at 393K and calcined at 973K, obtaining 0...

XRF elemental qualitative analysis was performed. By FTIR carbonates adsorbed species was observed. The presence of La2O3 and CaO phases was confirmed by XRD and BET surface area of the catalyst giving values less than 9m2 / g The measurement of the activity for La2O3/CaO cataluzador 15% was measured, it was performed in a microreactor quartz, using a feed rate of methane / oxygen ratio of 4:1 and the reaction temperatures of 923, 973 and 1023 K, resulting in a maximum conversion temperature of 1023K of 26.84% methane conversion and selectivity to C2 + of 38.17%.Los catalizadores de La2O3/CaO fueron preparados en diferentes porcentajes en peso de La2O3.Por el método de coprecipitación, descrito porRaO, se preparó el CaCO3 y luego éste se impregnó en una solución de La(NO)3.6H2O obteniéndose así el precursor del catalizador.Los precursores se secan a 393K, y se calcinan a 973K, obteniendo catalizadores 0-15% La2O3/CaO. Por FRX se realizó el análisis cualitativo elemental. Mediante FTIR se observó especies de carbonatos adsorbidas. La presencia de las fases de La2O3 y CaO se confirmó por DRX y se midió el área superficial BET del catalizador dando valores menores de 9m2/g La medición de la actividad para el cataluzador 15% de La2O3/CaO, se realizó en un microrreactor de cuarzo, usando una razón de alimentación de Metano/Oxigeno de 4:1 y a las temperaturas de reacción de 923, 973 y 1023 K, obteniéndose una conversión máxima a la temperatura de 1023K de 26.84 % de conversión de metano y una selectividad a C2+ de 38.17%.Universidad Nacional Mayor de San Marcos1998-09-14info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://revistasinvestigacion.unmsm.edu.pe/index.php/quim/article/view/3982Revista Peruana de Química e Ingeniería Química; Vol. 1 No. 1 (1998); 17-22Revista Peruana de Química e Ingeniería Química; Vol. 1 Núm. 1 (1998); 17-221609-75991726-2208reponame:Revistas - Universidad Nacional Mayor de San Marcosinstname:Universidad Nacional Mayor de San Marcosinstacron:UNMSMspahttps://revistasinvestigacion.unmsm.edu.pe/index.php/quim/article/view/3982/5484Derechos de autor 1998 A.
