Definitions
- the present invention relates to a method for producing methanol by reacting carbon monoxide, carbon dioxide, or a mixture thereof with hydrogen.
- Methanol is a very useful compound that is widely used as a synthesis raw material such as formalin, or as a solvent or fuel. Background art
- synthesis gas is used as a starting material.
- M A1 or Cr
- a catalyst composed of a support of a noble metal such as Pd or Rh or a Group VIII metal such as Ni on a carrier also exhibits activity in a methanol synthesis reaction using carbon monoxide or carbon dioxide as a starting material.
- the synthesis gas is introduced into the solvent in which the catalyst is suspended to carry out the reaction, so that the heat control is relatively easy and the methanol conversion is higher than in the gas phase method. Can be manufactured.
- both the gas phase method and the liquid phase method decrease the selectivity and the amount of produced methanol due to concurrent side reactions. There is a problem of doing.
- the present invention provides a method for producing methanol from carbon monoxide and Z or carbon dioxide and hydrogen in the presence of a catalyst having excellent activity and selectivity. It is for the purpose of. Disclosure of the invention
- FIG. 1 shows an X-ray diffraction pattern of the copper oxide containing ytterbium oxide obtained in Example 1.
- Figure 2 shows the X-ray photoelectron spectroscopy spectrum (Cu2p spectrum) of the reduced copper containing ytterbium oxide obtained in Example 1.
- Figure 3 shows the X of the reduced copper containing ytterbium oxide obtained in Example 1. Shows the X-ray photoelectron spectroscopy spectrum (Yb4d spectrum). BEST MODE FOR CARRYING OUT THE INVENTION
- the lanthanide compound-containing copper oxide used in the production of the catalyst used in the method of the present invention includes Dy (disposium), Ho (holmium), Er (erbium), and Tb (terbium). ), At least one compound of a lanthanide element selected from the group consisting of Tm (thulium), Yb (ytterbium) and Lu (lutetium), and copper nitrate and Z or chloride.
- the mixture obtained is mixed with a predetermined amount, and the obtained mixture is mixed with 150 to 650. C, preferably by heat treatment at 250-450.
- the compound of the lanthanide element can be selected from oxides, nitrates and chlorides of the lanthanide element. If the heating temperature exceeds 650 ° C., CuO and Z or oxides of Dy, Ho, Er, Tb, Tm, Yb or Lu are not preferred. On the other hand, when the above-mentioned heating temperature is lower than 150 ° C., the formation reaction of the lanthanide compound-containing copper oxide from various metal salts does not proceed smoothly, which is not preferable.
- the above heat treatment is performed by using a normal heating device such as an electric furnace, It is preferable to carry out the treatment while removing volatile decomposed products under a flow of gas such as nitrogen or air or under reduced pressure.
- the heating time is appropriately selected within the range of 1 minute to 50 hours.
- the copper oxide containing the lanthanide compound thus prepared was found to have a force of 20 to 16.0 to 16.8 in its X-ray diffraction spectrum. , 29.5-34.0 °, 37.8-39.5 °, 41.0-43.0 °, 54.6-57.0. It has characteristic peaks. These peaks are assigned to the plane indices 111, 222, 400, 331, and 440 of the cubic crystal, respectively. The axial length a of this crystal is about 9.2 to 9.8A.
- this La printer Roh I de compounds containing copper oxide, if it is a cubic system crystal having a composition similar to Ag? 0 8 (N0 3) Is recognized.
- the lanthanide compound-containing copper oxide (for example, i-type) is obtained from the X-ray diffraction spectrum shown in FIG. It is recognized that copper atoms and lanthanide atoms represented by M (for example, ytterbium atoms) are regularly arranged in a cubic crystal lattice of copper oxide containing a ytterbium compound). Is received. Therefore, the lanthanide compound-containing copper oxide is recognized as a compound in which copper atoms and lanthanide atoms (ytterbium atoms) are mixed at an atomic level.
- the lanthanide-containing reduced copper used in the method of the present invention can be prepared by reducing the lanthanide compound-containing copper oxide prepared as described above at a relatively low temperature. Can be. If the reduction temperature is too high, thinning occurs, and if the reduction temperature is low, the reduction does not proceed, so this reduction removes the lanthanide compound-containing copper oxide from 200 to 400 ° C, Preferably, it is carried out by contacting with a gas containing a reducing gas such as hydrogen at a temperature of 250 to 350 ° C.
