Abstract
A mesostructured material is described, which consists of at least two elementary spherical particles, each one of said particles comprising a mesostructured matrix based on aluminium oxide, said matrix having a pore diameter ranging between 1.5 and 30 nm, and an aluminium oxide content representing more than 46 wt. % of the mass of said matrix, which has amorphous walls of thickness ranging between 1 and 30 nm, said elementary spherical particles having a diameter D greater than 10 μm and less than or equal to 100 μm (10<D(μm)≦100). Said mesostructured matrix can also contain silicon oxide. Each spherical particle of the mesostructured material can also contain zeolite nanocrystals so as to form a mixed porosity material of both mesostructured and zeolitic nature. The preparation of said material is also described.
