Producción de hidrógeno por oxidación parcial de metano sobre espinelas de aluminato de níquel

Abstract

[ES] Durante las últimas décadas, el hidrógeno ha atraído la atención tanto de gobiernos como de empresas debido al rápido desarrollo que las pilas de combustible han mostrado, principalmente por sus posibles aplicaciones en el sector automovilístico, periodo durante el cual prácticamente todos los fabricantes de vehículos han mostrado sus prototipos empleando pilas de combustible. No obstante, la obtención de hidrógeno puro para la alimentación de las pilas de combustible presenta un problema ya que las fuentes existentes no están fácilmente disponibles o son difícilmente almacenables. Esto requiere que, al menos a corto plazo, el hidrógeno sea mayoritariamente adquirido mediante el reformado de hidrocarburos ligeros o hasta fracción gasolina. Las variantes subestequiométricas del catalizador NiAl2O4 son una opción interesante como alternativa para reducir costes de operación en el reformado catalítico, debido a que presentan estabilidad a baja temperatura y elevada dispersión del NiO en la estructura, lo cual regula la formación de partículas más grandes que reduzcan su actividad.
