Abstract
Porous materials are commonly used as catalyst supports in the processes of oxidation, hydrogenation and dehydrogenation at high temperature, corrosion in feed processing - corrosive environments at endothermic and exothermic reactions in particular, for this purpose, various types of corundum materials with high chemical inertness. Porosity materials due to the high porosity and the peculiar structure have specific properties dramatically different from those of the corresponding chemical composition of dense materials. There was obtained a highly porous cellular material of alumina carriers for catalysts. The filler used to be electro corundum, as reinforcing filler, forming on fire a bundle used porcelain. The samples were prepared by impregnating the ceramic slurry polyurethane foam (PUF), followed by drying and calcining at 1450°C. The porosity after firing was 60-65 %, the compressive strength of 3.5 MPa.
