Influence of a Zeolite-Based Cascade Layer on Fischer–Tropsch Fuels Production over Silicon Carbide Supported Cobalt Catalyst

In this work, selective production of middle distillate from synthesis gas was conducted over a cascade catalytic system in a single unit. Co/β-SiC was chosen as an efficient Fischer–Tropsch synthesis (FTS) catalyst (first layer) while proton-type H-ZSM-5 and H-βeta zeolites (second layer) were test...

Se eligió Co/β-SiC como catalizador eficiente de la síntesis de Fischer-Tropsch (FTS) (primera capa), mientras que las zeolitas H-ZSM-5 y H-βeta de tipo protón (segunda capa) se probaron para el subsiguiente hidroprocesamiento para producir un destilado medio. de ceras. Además, con el fin de comparar, se realizó un experimento de referencia FTS previo. Los materiales catalíticos se caracterizaron mediante Absorción Atómica, Análisis Termogravimétrico, Difracción de Rayos X, N 2adsorción-desorción, reducción a temperatura programada y desorción a temperatura programada. A partir de los resultados catalíticos, se observó una mejora distinguible de los productos de combustibles comerciales bajo la operación en cascada propuesta en comparación con la configuración independiente o la mezcla física. Independientemente del tipo de zeolita, se demostró que FTS sobre Co/β-SiC con mejora posterior da como resultado la eliminación completa de ceras, resolviendo la principal debilidad de un reactor de lecho fijo convencional. Además, además de una producción selectiva de gasolina, el concepto propuesto proporcionó una mejora significativa de los rendimientos de queroseno y diesel, particularmente cuando se incorpora zeolita H-βeta al sistema en cascada debido a su acidez suave y tamaño de poro más grande.Springer Link202220222017info:eu-repo/semantics/articletext/plainapplication/pdfhttp://hdl.handle.net/10578/29735reponame:RUIdeRA.
