ABSTRACT:
Catalyst comprising at least one zirconium oxide, characterized in that it consists, for at least 85% of its weight, of a thermally stable support with a specific surface greater than or equal to 150 m.sup.2 /g containing from 60 to 99 weight % of at least one zirconium oxide and from 40 to 1 weight % of at least one metal oxide of at least one metal chosen from the group consisting of metals from Groups V, VI and VII, noble metals such as ruthenium, osmium, rhodium, iridium and uranium, and the elements phosphorus, arsenic and sulphur, the support being obtained by the molten salts technique by introduction of a mixture of salts into a eutectic mixture of alkali metal nitrates or sulphates which, after dehydration, is maintained between 250.degree. and 550.degree. C., from 30 minutes to 5 hours.
