Set of high thermal stability medium porosity alumina comprises supports for catalysts, obtained by hydrolysis of aluminum source used with solvent and surfactant

The set of high thermal stability medium-porosity alumina comprises a blend of an aluminum source, an organic solvent, and a non-ionic surfactant derived from alkene polyoxides and an amine. An Independent claim is included for a process for preparing the alumina. The process undertakes hydrolysis of the aluminum source via a hydrolysing solution, yielding support materials for catalysts of processes requiring severe regeneration conditions.

El procedimiento comprende la mezcla de una fuente de aluminio con un disolvente orgánico, un surfactante no iónico derivado de polióxidos de alqueno y una amina, y la hidrólisis de la fuente de aluminio mediante la adición a la mezcla anterior de una disolución hidrolizante. Se obtienen materiales susceptibles de aplicación tanto como catalizadores como soporte de catalizadores para distintos procesos de interés industrial, especialmente aquellos que transcurren a temperaturas relativamente elevadas o requieren condiciones severas de regeneración.
