Summary 1. Study of the specific activities of Al2O3- NiO catalysts roasted at 400–750° for the decomposition of i-C3H7OH showed that there is optimum activity with respect to composition for NiO contents ranging from 5–15 moles per cent. 2. It was shown that the selectivities of the catalysts studied depend on composition; over a wide range of NiO contents only dehydration occurs, which indicates absence of free NiO. Dehydrogenating power appears only in catalysts of high NiO content and indicates the formation of a free-NiO phase. 3. It was shown that in coprecipitated NiO-A12O3 catalysts it is possible for the spinel NiAl2O4 to be formed at a temperature as low as 400° because of the intermolecular dehydration of the hydroxides. 4. The relation between specific surface and temperature of roasting was determined for these catalysts over the range 400–900°.
