CATALYST REDUCTION METHOD An improved method is disclosed for reducing platinum oxide in a catalyst with hydrogen during activation or regeneration of the catalyst by maintaining the temperature of the catalyst below 700.degree.F whenever the catalyst is contacted with a nonoxidizing atmosphere at any time prior to complete reaction of the platinum oxide with hydrogen to form elemental platinum, so that the platinum oxide is not reacted with hydrocarbon contaminants present in the nonoxidizing atmosphere. |
