Particles of active aluminium oxide hydrate are contacted with a molten carbon-contg. material, or a soln. and then heated to decompose the material without dehydrating the aluminium oxide hydrate, whereby a layer of active carbon is formed on the surface of the particles and the walls of fine pores contained in it. The resulting material is suitable for treatment of galvanoplastic baths, decolourisation of sugar solns., removal of undesired components from cigarette smoke, purification of petrol, chromatographic separation, purification of pharmaceuticals, use as catalyst or a catalyst carrier ect. |
