Abstract
1. Способ приготовления носителя на основе α-AlOдля катализаторов окисления этилена путем смешения гидроокиси алюминия с мелкокристаллическим бемитом, активированным кислотой с последующей сушкой и прокаливанием, отличающийся тем, что, с целью упрощения способа и получения носителя с улучшенными механическими свойствами, в состав носителя на стадии смешения вводят 20 - 50 вес.% стеклянного порошка с размером частиц 0,5 - 10 мкм.2. Способ по п.1, отличающийся тем, что прокаливание ведут при 1240 - 1260С.1. The method of preparation of the carrier based on α-AlO for catalysts for the oxidation of ethylene by mixing aluminum hydroxide with crystalline boehmite, activated acid, followed by drying and calcination, characterized in that, in order to simplify the method and obtain a carrier with improved mechanical properties, the composition of the carrier on 20-50% by weight of a glass powder with a particle size of 0.5-10 microns is introduced into the mixing stages. The method according to claim 1, characterized in that the calcination is carried out at 1240 - 1260C.
