New Aluminosilicate Materials with Hierarchical Porosity Generated by Aerosol Process

Abstract

This paper underlines the great advantage of using a spray-drying process (aerosol process) to synthesise new families of aluminosilicate materials with a hierarchical porosity from the microporous to the macroporous scales. In concrete terms, high aluminum content mesostructured solids, zeolite - mesostructured aluminosilicate composites and amorphous hierarchical aluminosilicate solids with micro, meso and macroporosity have been successfully synthesised. Notice that the latter family is characterised by non usual acidic properties in cumene cracking catalytic reaction. Such results open then new perspectives in the development of innovating acidic catalysts for hydrocracking reactions.
