FIELD: technical chemistry; catalyst carriers for various heterogeneous processes in chemical industry.
SUBSTANCE: proposed carrier has metal base made from chromium and aluminum alloy and/or metallic chromium and coat made from chromium of aluminum oxides or oxides of chromium, aluminum, rare-earth elements or mixture of them. Method of preparation of carrier includes forming of metal powder containing aluminum and other powder-like components and calcination of carrier at solid phase sintering point; used as additional component of metal powder is powder-like chromium; mixture thus obtained is subjected to mechanical activation and is placed in mold accessible for water vapor, after which it is subjected to hydro-thermal treatment and molded product is withdrawn from mold, dried and calcined at respective temperature; then additional layer of aluminum and rare-earth elements oxides or mixture of solutions and suspensions is applied on calcined product followed by drying and calcination.
EFFECT: increased specific surface; enhanced heat resistance of carrier.
