Abstract
A mesostructured aluminosilicate material is described, which consists of at least two elementary spherical particles, each one of said spherical particles consisting of a matrix based on silicon oxide and aluminium oxide, said matrix having a pore diameter ranging between 1.5 and 30 nm, a Si/Al molar ratio at least equal to 1 and amorphous walls of thickness ranging between 1 and 30 nm, said elementary spherical particles having a diameter D such that 10<D(μm)≦100. A method of preparing said material and its application in the spheres of refining and petrochemistry are also described.
