Definitions
- the present invention relates to a method for producing methanol by reacting a gas mixture which contains hydrogen and carbon monoxide and / or carbon dioxide over a catalyst.
- methanol can be produced from H 2 and CO and / or CO 2 on copper-containing catalysts. It is also known for this purpose to use catalysts which, in addition to copper, also contain zinc oxide, zirconium oxide and optionally further oxides (GB-A 2 151 498, US Pat. No. 5,254,520, Y. Nitta et al., Catal. Lett. 1994, 26, 345-354).
- the known catalysts often contain additives which make it difficult to dispose of or reprocess the spent catalyst.
- the object of the present invention to provide a process for the production of methanol with a higher space-time yield by using an improved catalyst, the catalyst preferably not containing any toxic or otherwise questionable components.
- the object is achieved by the method according to claim 1. It has surprisingly been found that excellent results can be achieved even with a catalyst having a simple composition of 10-70% Cu, 10-50% Zn and 20-80% Zr if the latter is essentially X-ray-amorphous. The percentages indicate the relative proportion of the metallic elements Cu, Zn and Zr, ie the sum of the three values is always 100%, regardless of whether there are any other elements.
- catalyst is understood to mean only the catalytically active substance in all the information relating to the composition. This can, of course, be applied to a carrier or assembled in some other way.
- a catalyst is referred to as “essentially X-ray amphib”, the X-ray diffraction pattern of which, like that of a liquid or a glass, has no discrete diffraction lines.
- the catalyst used according to the invention preferably contains 20-50% Cu, 10-40% Zn and 30-60% Zr.
- the catalyst is preferably prepared by coprecipitating a precursor from a solution of water-soluble copper, zinc and zirconium salts. This is washed and dried. and then calcined at 300-500 ° C. In this temperature range there is no appreciable crystallization of the amophene Catalyst precursor instead.
- the catalyst is expediently activated before use for the synthesis of methanol. This is achieved by heating in a hydrogen-containing atmosphere to a final temperature of 200 to 350 ° C.
- the catalyst is preferably first kept at a lower temperature in an inert atmosphere, for example under nitrogen or argon, and then gradually or continuously exposed to slowly increasing temperatures and hydrogen concentrations until the final temperature is reached.
- the chlorides or nitrates are preferably used as water-soluble copper, zinc and zirconium salts.
- the coprecipitation is preferably effected by adding an alkali metal hydroxide solution to the solution of the water-soluble copper, zinc and zirconium salts. The co-precipitation can take place continuously or discontinuously, whereby in any case an intensive mixing of the reactants must be ensured.
- the methanol synthesis itself can be carried out under the usual temperature and pressure conditions.
- the temperature is advantageously 200 to 320 ° C, preferably 220 to 280 ° C.
- the pressure is advantageously in the range from 1 to 10 MPa, preferably from 3 to 7 MPa.
- the methanol synthesis is preferably carried out at a space velocity (Gas Hourly Space Velocity, GHSV) of 3200 to 40,000 ml / (g-h) (based on normal conditions), particularly preferably at 5000 to 20,000 ml / (g-h).
- space velocity Gas Hourly Space Velocity, GHSV
- Example 1 contains the X-ray diffractograms of the catalyst before / after, ie before calcination, from Example 1 (curve 1) and comparative example (2), and the diffraction lines of the crystalline comparative substance (CU Q 2 Zno g ) 5 (CO 3 ) 2 (OH) 6 from the database of the "Joint Committee on Powder Diffraction Standards" (International Center for Diffraction Data, 1601 Park Lane, Swarthmore PA 19081, USA) [JCPDS 380154] (3).
- 2 contains the X-ray diffractograms of the catalysts from Example 1 (1) and Comparative Example (2) after the calcination and the diffraction lines of synthetic zincite (ZnO) [JCPDS 361451].
- the following examples illustrate the implementation of the method according to the invention:
- the catalyst had the following properties: BET surface area: 75 m 2 / g Cu surface area: 10.9 m 2 / g (determined by N 2 O chemiso ⁇ tion) Crystallite size: ⁇ 2 nm (x-ray amorphous), see X-ray diffractogram Fig. 2 (1).
- Example 2 Analogously to Example 1, a catalyst with the composition 40% Cu, 20% Zn, 40% Zr was produced, the corresponding nitrates being used as starting materials instead of the chlorides.
- the catalyst thus obtained had a BET surface area of 177 m 2 / g before the calcination and was completely radiopaque.
- the calcined sample was also completely X-ray and had a BET surface area of 62 m 2 / g Comparative example
- Example 1 a Cu / Zn / Zr catalyst with the composition 29% Cu, 23% Zn, 48% Zr, but without the addition of chromium, was produced: to a solution of 631 g of ammonium hydrogen carbonate in 30 l of water a solution of 317.4 g of copper (II) nitrate trihydrate, 294.5 g of zinc nitrate hexahydrate and 400.9 g of zirconyl nitrate dihydrate in 10 l of water was added at 60 ° C. while stirring vigorously to 60 ° C. . The mixture was stirred at 60 ° C for 1 h. The temperature was then kept at 80 ° C.
- the catalysts described in Examples 1 and 2 and Comparative Examples 1 and 2 were tested for their suitability for methanol synthesis.
- the reaction was carried out in fixed bed microreactors (18 mm 0).
- the CO + CO 2 conversion, the yield of methanol, the methanol selectivity and the space-time yield were determined.
- the analysis of the reaction products was carried out by o «- / me gas chromatography.
- the catalysts were activated in situ as follows: The reactor was slowly heated to 130 ° C. under nitrogen (0.8 MPa). Then 2% hydrogen was added to the nitrogen and the temperature was raised to 200 ° C. at 20 K / h. After 16 hours, the hydrogen content was increased to 12%, the temperature was raised to 240 ° C. and held at this level for 2 hours.
- the methanol synthesis was carried out at 250 ° C and 5 MPa.
- a synthesis gas mixture of 32 vol.% Carbon monoxide, 5 vol.% Carbon dioxide and 63 vol.% Hydrogen was used as the starting material.
- the space velocity was 8000 ml / (gh).
- the results (conversion, yield, selectivity and space-time yield) are summarized in Table 1 below. These are the current values after a reaction time of 49 hours, i.e. after reaching a steady state.
- Example 2 Analogously to Example 2, further catalysts of different compositions were produced.
- the model Polytron® PT45-80 was used as a stirrer for the continuous coprecipitation.
- the composition in% by weight and the precipitation conditions (temperature ⁇ , pH, concentration c, stirring frequency v and metering speed ⁇ ) are summarized in Table 2 below.
