  • Method of preparing granulated activated alumina
    Patent number: 4166100
    Abstract: 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.degree. to 600.degree. 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 aluminium oxide, and hydrated at a temperature of 20.degree.-100.degree. C. and 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.degree. to 150.degree. C., granulated, dried at a temperature of 20.degree. to 150.degree. C., and calcined at a temperature of 400.degree. to 600.degree. C.
