Abstract
Способ получения носителя для катализаторов на основе оксида алюминия, включающий смешение порошков гидраргиллита и псевдобемита, пластификацию раствором азотной кислоты, формование, сушку и термообработку сформованных гранул, отличающийся тем, что, с целью получения носителя с уменьшенной закоксовываемостью, высушенные гранулы перед стадией термообработки обрабатывают парами воды при 120 - 250C и давлении 2,5 - 50 атм и термообработку ведут при 550 - 800C.A method of obtaining a carrier for catalysts based on aluminum oxide, including mixing powders of hydrargillite and pseudoboehmite, plasticization with a solution of nitric acid, molding, drying and heat treatment of the formed granules, characterized in that, in order to obtain a carrier with reduced coking, the dried granules are treated with pairs water at 120 - 250C and a pressure of 2.5 - 50 atm and heat treatment is carried out at 550 - 800C.
