Abstract
The present invention concerns zeolites with hierarchical porosity having a molar ratio Si/Al of between 1 and 1.4, inclusive, of which the average diameter, as a number, is between 0.1 μm and 20 μm, having controlled and optimized crystallinity, and having mesoporosity such that the mesoporous outer surface area is between 40 m·gand 400 m·g. The present invention also concerns the method for preparing said zeolites with hierarchical porosity.
