Patent attributes
A process for the preparation of a catalyst comprising palladium, a porous support with a specific surface area in the range 140 to 250 m2/g, said catalyst being prepared by a process comprising the following steps:a) preparing a colloidal solution of palladium oxide or palladium hydroxide in an aqueous phase;b) adding said solution obtained from step a) to said porous support at a flow rate in the range 1 to 20 litre(s)/hour; said porous support being contained in a rotary impregnation device functioning at a rotational speed in the range 10 to 20 rpm;c) optionally, submitting the impregnated porous support obtained from step b) to a maturation;d) drying the catalyst precursor obtained from step b) or c);e) calcining the catalyst precursor obtained from step d).
