Materiales a base de óxido, su procedimiento de preparación y composiciones de catalizador que contienen estos materiales

Abstract

La presente invención se relaciona con materiales óxidos, con un procedimiento para su preparación, con composiciones catalíticas que los contienen y con el uso de las composiciones catalíticas en un procedimiento para el craqueo catalítico de un stock de alimentación hidrocarbonado. Son ejemplos de materiales laminares que se hinchan o expanden en presencia de agua y/o de cationes intercalantes apropiados, las arcillas, los fosfatos y fosfonatos de zirconio, los hidroxicarbonatos tales como la hidrotalcita, las sílices tales como kanemita, magadita y keniaíta, los sulfuros de metales de transición, el grafito y los hidróxidos laminares. Las capas individuales de estos materiales se unen entre sí por enlaces débiles, tales como enlaces de hidrógeno y fuerzas electrostáticas, que se rompen fácilmente cuando la fuerza intercalante o la energía de solvatación de los cationes supera la fuerza de atracción entre las capas.
