FIELD: chemistry.
SUBSTANCE: invention relates to making sorbents and supports for supported catalysts and can be used in preparing catalysts for different catalytic processes. Described is a method of making supports for catalysts based on fibreglass, involving treatment by single- or multiple incipient wetness impregnation with aqueous solutions of modifying precursors in form of silica sol, aluminium hydroxide sol, aluminium oxynitrate, or single- or multiple immersion in an alcohol solution of tetraethoxy silane with hydrolysis in water vapour at 70-80°C for 3 hours, followed by drying at 120°C for 1 hour and calcination at 550°C for 4 hours. Described also is a catalyst support based on fibreglass obtained using the disclosed method and containing up to 30 wt % deposited catalyst from the mass of fibreglass or up to 20 wt % deposited Al2O3 from the mass of glassfibre, having specific surface area of up to 60 m2/g, and mean pore diameter of 50-60 Ǻ.
EFFECT: linear increase of specific surface area of the support from the amount of the deposited additive.
