Embodiment 1
[0056] Mixed metal oxides were prepared by mixing the following ingredients using a mixer: 1.06 kg hydroxy-cobalt carbonate (28% by weight Co), 1.14 kg MoO 3 (65.7% Mo by weight), 269g potassium carbonate (99.5% purity), 375g clay binder in the form of attapulgite (LOI=20.5%), acicular clay mineral composed of manganese-aluminosilicate (the side dimensions higher than 1 nm) and 500ml demineralized water. The resulting mixture had an LOI of 40.1% by weight and was extruded into a 3 mm trilobate shape. Subsequently, the samples were dried overnight at 120°C.
Embodiment 2
[0058] Using H 2S (60 volume%) and N 2 (40% by volume) 50 g of the sample obtained in Example 1 were vulcanized. To avoid oxidation, samples were stored under inert gas. The total amount of sulfur fed (expressed as mol sulfur / mol metal) was 6.0. The atomic ratio of sulfur to metal in the sample was found to be 2.3. The catalyst obtained was used for alcohol synthesis from synthesis gas using the following procedure:
[0059] 4.2 grams of ground sample (particle size between 0.4 and 0.6 mm) were loaded into a sealable stainless steel reactor with an internal diameter of 16 mm. The temperature of the catalyst within the catalyst bed (located in the isothermal region of the oven) was monitored using a thermocouple (3 mm in diameter).
[0060] All manipulations were performed in a glove box to prevent catalyst oxidation. The reactor was then pressurized to 95 bar with nitrogen and heated under 50.7% H 2 , 31.9% CO and 17.4% N 2 The mixture was heated to 150 °C in the prese...
Embodiment 3
[0062] Mixed metal oxides were prepared by mixing the following ingredients using a mixer: 1.691 kg hydroxy-cobalt carbonate (44.6% by weight Co), 0.921 kg MoO 3 (65.7% Mo by weight), 352g potassium carbonate (99.5% purity), 491g attapulgite (LOI = 20.0%), acicular clay mineral composed of manganese-aluminosilicate (with lateral dimensions higher than 1 nm ) and 1700ml demineralized water. The resulting mixture had an LOI of 49.6% by weight and was extruded into a 3 mm trilobate shape. Subsequently, the samples were dried overnight at 120°C. Using H 2 S (60 volume%) and N 2 (40% by volume) to vulcanize the resulting sample. To avoid oxidation, samples were stored under inert gas. The total amount of sulfur fed (expressed as mol sulfur / mol metal) was 6.0. The atomic ratio of sulfur to metal in the sample was found to be 1.5. The catalyst obtained was used for alcohol synthesis from synthesis gas using the procedure described in Example 2. The results are shown in the ta...
