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 m2·g−1 and 400 m2·g−1. The present invention also concerns the method for preparing said zeolites with hierarchical porosity.
