Реферат: The method of preparing granulated activated alumina consists in that alumina trihydrate is decomposed by bringing it in contact with a bed of a solid heat carrier having the temperature of 350° to 600° C., the contact time being from 0.05 to 0.5 second, to obtain a product of decomposition in the form of amorphous aluminium hydroxide. Said decomposition product is mixed with water into a suspension having the concentration of 100-500 g/liter, calculating with reference to alumin ium oxide, and hydrated at a temperature of 20°-100° C. vand the pH of 5 to 12 for 0.5 to 10 hours. The hydrated decomposition product is then treated with an acid, that can form water-soluble basic salts of aluminium, at a temperature of 20° to 150° C., granulated, dried at a temperature of 20° to 150° C., and calcined at a tempera ture of 400° to 600° C. The granulated activated alumina can be used as an adsorbing material, as a catalyst, or a support for active components in chemical and petrochemical industry.
