Abstract
Al2O3 и χ-Al2O3 при термообработке продукта термохимической активации тригидрата алюминия.Industrial microspherical aluminum hydroxide thermo-chemical activation products which represent mixtures of gibbsite, boehmite and amorphous aluminium hydroxide were investigated. At the stage of active component anchoring in the process of alumina/chromia catalysts preparation aggregation of granules takes place as a result of aluminum hydroxochromate hydrolysis and alumogel formation which serves as binding agent. On purpose to prevent the gel formation method of gibbsite to mixture of γ-Al2O3 and χ-Al2O3 transformation by thermal treatment of aluminum hydroxide thermochemical activation products was offered.
