Poster summary

The use of magnesium aluminate as a carrier of catalysts in different catalytic processes is of significant practical interest due to neutral acid-base characteristics of the surface and its high thermal stability. Traditional methods of obtaining of alkali-earth metals aluminates are a ceramic (with high-temperature sintering) and a sol-gel. We previously published the results of obtaining of alkali-earth metals aluminates using a hydrothermal treatment of a suspension of the product of thermal activation of Gibbsite in salts solutions with the production of powder material after mild calcining of formed gels [1-3], while granular supports and catalysts are used in catalytic processes. The purpose of the work is to obtain granules of the carrier based on the magnesium aluminate with the spinel structure with high values of the specific surface area, mechanical strength and volume of pores
