FIELD: inorganic compounds technologies.
SUBSTANCE: invention relates to production of activated alumina appropriate as catalyst carrier for petrochemical and organic synthesis, in particular as reforming catalyst carrier. Process comprises continuous precipitation of aluminum hydroxide with pseudoboehmit structure from basic aluminum sulfate solution by neutralization with alkali reagent, filtration, autoclave treatment of resulting aluminum hydroxide precipitate in aqueous ammonia solution at pH 10.0-11.0 of reaction mixture, 135-145°C, and agitation time 1.0-2.0 h, washing of precipitate with chemically desalted water, drying, and final heat treatment.
EFFECT: improved quality of activated alumina and reduced consumption of water in washing of final product.
