FIELD: sorbents. SUBSTANCE: high-strength high-porous aluminosilicate composites suitable as adsorbents and catalyst carriers are composed of montmorillonite and/or its sodium form and X- ray-amorphous thermally dispersed alumina and prepared by adding dry thermally dispersed alumina to suspension of pretreated with nitric acid hydrated montmorillonite and/or its sodium form followed by treating resulting mixture with nitric acid. EFFECT: increased strength of material. 5 cl, 7 ex
