Abstract
Process for preparing platinum granules in an alumina catalyst suitable for the hydrogenative transformation of gasoline over an extended period of time, characterized by dehydrating bayerite to form absorbent alumina granules containing eta alum; by increasing the total volatile matter of the absorbent alumina granules, up to about 15% to 22%, by weight of the alumina, by subjecting said granules to a gas stream having a temperature comprised between 15.6 and 37.8º C. approximately and contains sufficient water vapor to provide a relative humidity of the order of 51% to 100%; by subjecting the steam-treated granules to a series of vacuum purge cycles and by treating with a gaseous acidic atmosphere selected from sulfur dioxide, carbon dioxide, nitric oxide and mixtures thereof, to replace an acidic gas, practically completely, by air, in the pores of the granule; by impregnating an aqueous solution of a platinum-containing compound, in the treated absorbent alumina granules, and by heating the granules at an elevated temperature, to dry them.
