Abstract

The thermal decomposition, the nickel oxidation and other thermal changes in commercial NiO/Al₂O₃ catalysts were studied over the temperature range 20-1000°C. The thermal analysis (TG and DTA) results of the reduced steam-re-forming catalysts were used to determine the extent of reduction of the catalyst to the active metal (nickel). The metallic nickel content in the reduced catalyst samples determined by the rapid thermal technique compared fairly quite well with results obtained by the longer chemical analysis method. The thermal analysis of the reduced steam-re-forming catalysts each showed, regardless of reduction conditions, one exothermic peak with a corresponding gain in weight in the temperature range 20-1000°C.
