Claims (1)

1. Способ приготовления алюмооксидного носителя для катализаторов, включающий формование гранул из алюмооксидной массы, пептизированной азотной кислотой, последующую термообработку гранул, отличающийся тем, что гранулы формуют в виде экструдатов или шариков, а в качестве алюмооксидной массы используют глинозем с пластифицирующей, выгорающей и модифицирующей добавками, термообработку осуществляют при температуре 1000 - 1200oC, при этом в качестве пластифицирующей добавки используют активный оксид и/или переосажденный гидроксид алюминия, в качестве выгорающей добавки - графит, в качестве модифицирующей добавки - оксиды циркония и/или лантана в виде азотнокислого раствора, и алюмооксидная масса имеет следующий состав, мас.%:
Активный оксид и/или переосажденный гидроксид алюминия (в пересчете на Al2O3) - 5 - 50
Графит - 2 - 10
Оксиды циркония и/или лантана в виде азотнокислого раствора - 0,3 - 1,0
Глинозем - Остальное
2. Способ по п.1, отличающийся тем, что модифицирующая добавка содержит ZrO2 и La2O3 в массовом соотношении ZrO2 : La2O3 = 0,6 - 1,5 : 1.
1. A method of preparing an alumina carrier for catalysts, comprising forming granules from an alumina mass peptized with nitric acid, subsequent heat treatment of the granules, characterized in that the granules are molded in the form of extrudates or balls, and alumina with plasticizing, burning and modifying additives is used as the alumina mass heat treatment is carried out at a temperature of 1000 - 1200 o C, while the active oxide and / or reprecipitated aluminum hydroxide are used as plasticizing additives, graphite as a burnable additive, zirconium and / or lanthanum oxides in the form of a nitric acid solution as a modifying additive, and the alumina mass has the following composition, wt.%:
Active oxide and / or reprecipitated aluminum hydroxide (in terms of Al 2 O 3 ) - 5 - 50
Graphite - 2 - 10
Zirconium and / or lanthanum oxides in the form of a nitric acid solution - 0.3 - 1.0
Alumina - Else
2. The method according to claim 1, characterized in that the modifying additive contains ZrO 2 and La 2 O 3 in a mass ratio of ZrO 2 : La 2 O 3 = 0.6 - 1.5: 1.
