Definitions
- the treatment can be done, in this case, on a solution or suspension of the product or even on a powder.
- these treatments can be done before or after the washing step described above.
- the reduction treatment can be carried out by gas using a reducing gas which can be chosen from hydrogen, carbon monoxide or hydrocarbons, this gas can be used in any volume concentration. It is particularly possible to use hydrogen diluted in argon. In the case of a reduction treatment according to the latter type, this is done after the aforementioned washing step.
- the treatment is carried out at a temperature which is at most 200 ° C., preferably at most 180 ° C.
- the duration of this treatment can be between 0.5 and 6 hours in particular.
- calcination can optionally be carried out as described above.
- the method of the invention can also be implemented according to a second embodiment which will now be described.
- the first step consists in depositing gold and, where appropriate silver, platinum, palladium or copper, on the compound based on cerium oxide by impregnation or by ion exchange.
- the impregnation method is well known. Preferably dry impregnation is used.
- EXAMPLE 11 An example of the preparation of a catalyst in the form of granules is given here. 21 g of granules of cerium oxide (Ce0 2 ) / alumina (Al 2 0 3 ) 90/10 by weight of oxide and specific surface 140 m 2 / g are placed in a column. This column is connected by a circulation system to a reactor (1) containing 125 g of water. At the same time, 0.4 g of HAuCI 4 , 3H 2 0 is dissolved in a reactor (2) containing 125 g of water. The solution contained in the reactor (1) is circulated through the column containing the Ce0 2 / Al 2 0 3 granules with a flow rate of 10mL / min.
- the cake obtained is redispersed in a NaOH solution at pH 11, the volume of which is equivalent to that of the mother liquors eliminated during the first filtration step.
- the suspension is kept stirring for 20 minutes. This basic washing procedure is repeated 2 more times.
- the cake obtained is finally redispersed in a volume of water equivalent to the volume of mother liquor eliminated during the first filtration and then filtered under vacuum.
- the washed cake is filtered under vacuum and then calcined for 2 hours at 200 ° C. in air.
- the analyzes carried out on the catalyst give the results which appear in Table 1 below.
