FIELD: catalyst carriers for conversion of natural gas, liquid phase reduction of non-saturated hydrocarbons, aromatic nitro-compounds, aldehydes, ketones, carboxylic acid, etc. ^ SUBSTANCE: articles from high-porous ceramic materials are produced by regeneration of structure of foamed reticulated foam polyurethane by application of ceramic powder containing filler and aluminum oxide powder which is active to sintering with addition of binder; then, base is burnt-out and remaining ceramic carcass is heated to temperature of 1450-1500 C. Total porosity of ceramic article is 85-95% at open porosity of strips laid between cells of 20-30%; strips have pores of 1-2 mcm in size. Specimens withstand static load of 0.5 to 2.0 Mpa depending on composition and modes of heat treatment. ^ EFFECT: enhanced efficiency. ^ 1 tbl |
