CA 2239142
The invention relates to amorphous, microporous mixed oxides characterised in that they have, in dry form, a confined pore distribution (half width < ~ 10 % of the pore diameter) of micropores in the range < 3nm in diameter; a total surface of between 20 and 1000 m2/g and a proportion of 0.1-20 % by weight of non-hydrolysable organic groups. The invention also relates to a process for preparing said oxides.
L'invention concerne des oxydes mixtes microporeux amorphes caractérisés en ce qu'ils possèdent, sous forme sèche, une étroite répartition des pores (largeur de valeur moyenne < ± 10 % du diamètre de pore) de micropores dans la plage < 3nm de diamètre, une surface totale comprise entre 20 et 1000 m?2¿/g et renferment une proportion comprise entre 0,1 et 20 % en poids de groupes organiques non hydrolysables. L'invention concerne également un procédé de production de ces oxydes.
