Abstract
Procedimiento para la disociación térmica de hidrato de cloruro de aluminio con calcinación a óxido de aluminio empleando un estado fluidificado con capa fluidificada muy ahuecada, que está unida con un graviente de la concentración de los sólidos desde abajo hacia arriba así como extracción de los sólidos junto con los gases en la parte superior de la cuba del reactor(zona de fluidificación), donde el hidrato de cloruro de aluminio alimentado antes de la introducción en la zona fluidificada se pone en contacto con gases para la disociación como mínimo parcial y después se conduce a la zona fluidificada, que separa con los gases los sólidos extraídos en la parte superior de la zona fluidificada y los introduce en una zona de residencia fluidificada y los introduce en una zona de residencia fluidificada con velocidad del gas más reducida.
