NiMo-124 The catalysts were prepared according to the Dutch Patent 123195 (17). The alumina carrier was impregnated first with nickel. Two final calcination temperatures were applied, 480 and 650°C. These samples were impregnated with molybdenum. Final calcination temperatures 480 and 650°C. The composition of the four catalysts, which were obtained was 12 wt% M0O3 and 4 wt% NiO, The catalysts are indicated by the applied calcination temperatures after each impregnation e.g. NiMo-124 480/480. 

Nickel Promoted Catalysts. Nickel containing catalysts are known to be sensitive for too high temperatures. The Dutch patent 123195 (17) claims that active nickel-molybdenum-alumina catalysts are obtained, when nickel is impregnated first. The calcination is critical however. According to this patent, catalysts calcined at 480 are twice as active as catalysts, calcined at 650°C.
