Properties and structure of NiO-AlO catalysts 3. A study of the relation between composition, magnetic properties and activity.

In a magnetic study of the coprecipitated NiO-AlO catalysts containing up to 59 mole % NiO, which had been subjected to a thermal treatment at 400‡, 600‡ and 750‡, the values of χ, Μ and δ were determined, and it was shown that: We established a good correlation of the magnetochemical data with the results of measurement of the activity [1] and of the roentgenographic determination of the structure [2]. It was shown that the extremal region in the graphs of magnetic properties - composition is the optimal one for the dehydrating activity of the catalysts. [ABSTRACT FROM AUTHOR]
