Embodiment 1
[0038] Embodiment 1 (comparison)
[0039] According to WO-A-01 / 36093, the nickel catalyst is prepared by mixing various solutions of salts, silicates, and sodium carbonate containing nickel, iron, and aluminum oxide at a temperature of 95 ° C in a fully stirred Mix in the settling vessel. The resulting slurry had a pH of approximately 7.5 and precipitation was complete after 1 hour. After washing the precipitate, the catalyst precursor was filtered and dried in an oven at 110°C. The catalyst is activated with hydrogen and passivated in the presence of air. The composition and physical properties of the obtained catalysts are listed in Table 1.
Embodiment 2
[0040] Embodiment 2 (comparison)
[0041] The various solutions containing salts of nickel and alumina, silicates, and sodium carbonate were mixed in a well-stirred settling vessel at a temperature of 95°C. The resulting slurry had a pH of approximately 7.5 and precipitation was complete after 1 hour. After washing the precipitate, the catalyst precursor was filtered and dried in an oven at 110°C. The catalyst is activated with hydrogen and passivated in the presence of air. The composition and physical properties of the obtained catalysts are listed in Table 1.
Embodiment 3
[0043] Various solutions containing salts such as nickel, cobalt, and alumina, silicate, and sodium carbonate were mixed in a well-stirred settling vessel at a temperature of 95°C. The resulting slurry had a pH of approximately 7.5 and precipitation was complete after 1 hour. After washing the precipitate, the catalyst precursor was filtered and dried in an oven at 110°C. The catalyst is activated with hydrogen and passivated in the presence of air. The resulting material contains 64wt.% Ni, 25wt.% SiO 2 , 2wt.%Al 2 o 3 and 0.3wt.% Co. Other physical properties of the resulting catalyst are listed in Table 1.
