N2 - A series of nickel-alumina catalysts with a range of Ni/Al ratios have been made by first precipitating the alumina component and then the nickel component. The effect on the properties of these samples of various pretreatments have been examined and the results have been compared with those for equivalent coprecipitated materials. At higher Ni/Al ratios, the sequentially prepared materials contain two phases and the resultant catalyst contains large Ni crystallites. This contrasts with coprecipitated samples where a single phase is obtained. A model for the catalysts is proposed.
