Abstract
Способ получения гранулированной активной окиси алюминия, включающий приготовление пластифицированной массы из гидроокиси алюминия псевдобемитной структуры, формование в водном растворе, содержащем аммиак, сушку и прокаливание полученных гранул, отличающийся тем, что, с целью повышения прочности гранул, в качестве водного раствора для формования используют смесь 7 - 12%-ного водного аммиака и 2 - 14%-ного раствора азотнокислого или солянокислого аммония.The method of obtaining granulated active aluminum oxide, including the preparation of plasticized mass of aluminum hydroxide pseudo-boehmite structure, molding in an aqueous solution containing ammonia, drying and calcining the obtained granules, characterized in that, in order to increase the strength of the granules, a mixture is used as an aqueous solution for molding 7 - 12% aqueous ammonia and 2 - 14% aqueous solution of ammonium nitrate or hydrochloric acid.
