Abstract

La presente invención se relaciona con la preparación de arcillas aniónicas multimetálicas (AMs), además de un procedimiento para la obtención de una serie de óxidos mixtos multimetálicos derivados de la descomposición térmica de las arcillas aniónicas preparadas de acuerdo a la invención. En esta invención se describen características físicoquímicas de las AMs. Debido a que existen una gran variedad de posibles aplicaciones comerciales a gran escala, se requieren nuevos procesos que proporcionen alternativas sencillas y económicamente viables, en los cuales la producción del material se lleve a cabo de manera continua, cumpliendo también con los requisitos ambientales. Estos materiales pueden utilizarse como catalizadores básicos heterogéneos en reacciones de química fina, en el campo de la medicina, para el control de las emisiones de SOx y NOx entre otras aplicaciones.
