Abstract

L'invention se rapporte à la chimie. Elle concerne une poudre d'aluminosilicate amorphe composée d'agrégats de particules sphéroïdales contenant une portion centrale de silice, d'aluminosilicate ou d'un ou plusieurs oxydes métalliques réfractaires, un revêtement autour de cette portion centrale d'un aluminosilicate hydraté amorphe, caractérisée par des particules sphéroïdales poreuses de 3 à 90 nanomètres, un revêtement autour de la portion centrale d'au moins 0,5 nanomètre d'épaisseur d'un aluminosilicate hydraté amorphe ayant un rapport molaire Si:Al compris entre 1:1 et 19:1, la poudre ayant une surface spécifique de 30 à 750 m**2/g, une masse volumique apparente de 0,5 g/cm** 3 ou plus, et un diamètre uniforme des pores entre les particules sphéroïdales compris entre 20 et 150 Angstrom , cette uniformité étant telle que 90 % du volume des pores sont formés de pores d'une grosseur comprise entre 0,6 D et 1,4 D, où D est le diamètre médian des pores. Utilisation pour la catalyse, en particulier dans le raffinage du pétrole.The invention relates to chemistry. It relates to an amorphous aluminosilicate powder composed of aggregates of spheroidal particles containing a central portion of silica, of aluminosilicate or of one or more refractory metal oxides, a coating around this central portion of an amorphous hydrated aluminosilicate, characterized by porous spheroidal particles of 3 to 90 nanometers, a coating around the central portion at least 0.5 nanometer thick of an amorphous hydrated aluminosilicate having an Si: Al molar ratio of between 1: 1 and 19: 1, the powder having a specific surface area of 30 to 750 m ** 2 / g, a bulk density of 0.5 g / cm ** 3 or more, and a uniform pore diameter between the spheroidal particles of between 20 and 150 Angstroms, this uniformity being such that 90% of the pore volume is formed by pores with a size between 0.6 D and 1.4 D, where D is the median diameter of the pores. Use for catalysis, in particular in petroleum refining.
