- 1. Process for preparing a catalyst, comprising impregnating a support with a solution of a platinum derivative and an inorganic cobalt salt in quantities such that the Pt/Co ratio expressed in gram-atom/gram-atom is between 1/9 and 9/1 and the sum of the weights of the two metals is between 1 and 10% of the weight of the support, evaporating the solvent, and heating the impregnated support to a temperature between 400.degree. and 500.degree. C. for 4 to 8 hours in a stream of hydrogen; the support is iron-free charcoal having a specific surface area greater than 1000 m.sup.2 /g, the platinum derivative is chloroplatinic acid, the cobalt derivative is hydrated cobalt nitrate, and the solvent is an aromatic hydrocarbon containing 1 to 5% of an aliphatic alcohol.
