Claims (8)

1. Способ получения активного оксида алюминия из технического гидроксида алюминия с использованием связующего пластификацией, формованием, сушкой и термообработкой, отличающийся тем, что в качестве связующего используют активный гидроксид алюминия, пластификацию проводят в две стадии: на первой стадии к техническому гидроксиду алюминия добавляют азотную кислоту и воду с кислотным модулем 0,1 - 0,9, перемешивают не более 1 часа, на второй стадии вводят связующее в количестве 10 - 40 мас.% и перемешивают не более 1 часа.1. A method of producing active alumina from industrial aluminum hydroxide using a binder by plasticization, molding, drying and heat treatment, characterized in that active aluminum hydroxide is used as a binder, plasticization is carried out in two stages: in the first stage, nitric acid is added to the technical aluminum hydroxide and water with an acid module of 0.1-0.9, is stirred for no more than 1 hour, in the second stage a binder is added in an amount of 10-40 wt.% and mixed for no more than 1 hour. 2. Способ по п.1, отличающийся тем, что в качестве связующего используют переосажденный гидроксид алюминия. 2. The method according to claim 1, characterized in that the re-precipitated aluminum hydroxide is used as a binder. 3. Способ по п.1, отличающийся тем, что в качестве связующего используют гидроксид алюминия, являющийся продуктом термомеханохимической активации. 3. The method according to claim 1, characterized in that as a binder use aluminum hydroxide, which is a product of thermomechanical activation. 4. Способ по п.1, отличающийся тем, что в качестве связующего используют химически активированный гидроксид алюминия. 4. The method according to claim 1, characterized in that chemically activated aluminum hydroxide is used as a binder. 5. Способ по п.1, отличающийся тем, что технический гидроксид алюминия перед пластификацией подвергают размолу до частиц размером 5 - 10 мкм. 5. The method according to claim 1, characterized in that the technical aluminum hydroxide before plasticization is subjected to grinding to particles with a size of 5 to 10 microns. 6. Способ по п.1, отличающийся тем, что, с целью получения носителя с бидисперсной пористой структурой, сформованные гранулы прокаливают при 460 - 650oС.6. The method according to claim 1, characterized in that, in order to obtain a carrier with a bidispersed porous structure, the formed granules are calcined at 460 - 650 o C. 7. Способ по п.1, отличающийся тем, что, с целью получения крупнопрористого носителя, термообработку ведут при 850 - 1100oС.7. The method according to claim 1, characterized in that, in order to obtain a large-porous carrier, heat treatment is carried out at 850 - 1100 o C. 8. Способ по п.1, отличающийся тем, что, с целью получения высокотемпературного носителя, термообработку ведут при 1100 - 1300oС.8. The method according to claim 1, characterized in that, in order to obtain a high-temperature carrier, heat treatment is carried out at 1100 - 1300 o C.
