Abstract

This paper explores the catalytic system “Ni-Al-O coating - Sandvik 0C-404 strip steel” obtained by the acti-vated thermo-chemical condensate deposition method.

After the thermal, hydrothermal and hydrother-mal-thermal treatment, adhesion, resistance to aggressive environments, chemical and phase composition, crystallite size and other parameters were determined. All coating surface phases for all three methods were obtained in the nanocrystalline range. As a result of hydrothermal process-ing, the coating had a partly hydrotalcitic structure.

The developed catalysts have excellent adhesion, are chemically stable; in addition, they are technologically repetitive. The system “Ni-Al-O coating - Sandvik 0C-404 strip steel” can be used as a commercial catalyst for gasifi-cation and steam reforming processes. Application of such system would reduce the catalytic converters’ volume, process temperature and energy demand.
