Definitions
- the process according to the invention is not subject to any restrictions in terms of the solution provided in step a). Accordingly, the process according to the invention may employ either a single solution comprising a single compound which comprises both the alkali metal and the transition metal or a solution comprising a plurality of compounds which comprise an alkali metal or a plurality of alkali metals and a transition metal in oxidised form or a plurality of transition metals in oxidised form. When a plurality of solutions are employed then these may comprise the same alkali metal/transition metal in oxidised form or the same alkali metals/transition metals in oxidised form or different alkali metals/transition metals in oxidised form.
- the transition metal is tungsten.
- the drying is followed by a calcining.
- the calcining is preferably carried out at temperatures of 400°C or more.
- the calcining is preferably performed such that the temperature is increased from the value during the drying to the final calcining temperature at a heating rate of about 5°C/min. This temperature is then maintained for several hours, preferably for up to three or more hours.
- the filtercake may also be commixed prior to the drying and/or calcining, preferably using a kneader, for example a laboratory batch kneader.
- the process according to the invention is accordingly not subject to any restriction in terms of the sequence of the steps b') drying and/or calcining and b") commixing the laden support material, and the number of times these steps are performed.
- the process according to the invention further comprises the steps, preceding the shaping, of b') drying and/or calcining of the laden support material and
- the steps a) to b), a) to b') or a) to b") are accordingly repeated with the laden support material obtained from step b), b') or b").
- the steps a) to b") are repeated with the laden support material obtained from step b").
- the support material in the step b) to be repeated is the laden support material obtained from the step b") which was performed prior to the step b) to be repeated.
- the catalysts produced or obtainable by the process according to the invention and the catalyst according to the invention are suitable for the production of alkyl mercaptans from alkyl alcohols and hydrogen sulfide.
- the procedure employed therefor was as follows: 62.2 g of tungstic acid were suspended in 130.4 g of ammonia solution and dissolved by stirring for approximately 30 minutes. 89.3 g of a solution of cesium hydroxide in water (70%) were added to this solution and the resulting solution was stirred for approximately 23 to 24 hours.
- the aluminium oxide was initially charged into a glass vessel that was evacuated to 150 mbar. By opening the tap the impregnation solution was suctioned off until a supernatant of impregnation solution of approximately 4.5 cm was present over the entire aluminium oxide. The glass vessel was vented and the support was then incubated in the solution for approximately 15 minutes.
- the chopped extrudates were allowed to fall onto a drying belt and predried at 60°C before being heated to 120°C at a heating rate of 1 °C/min in a muffle furnace and dried at this temperature for 3 hours.
- the dried extrudates were calcined immediately afterwards by increasing the temperature to 455°C at a heating rate of 5°C/min and maintaining this temperature for 3 hours.
