摘要: A start-up procedure wherein a halogenated rhenium-containing catalyst, to improve its performance in reforming naphtha feeds, is contacted with water, added with the hydrogen and said feed. During the start-up period, preferably on initiation of the start-up period after aromatics production has begun, a naphtha feed, hydrogen and water are passed cocurrently through the several reactors of a reforming unit and reacted over the halogenated rhenium-containing catalyst. Water is generally added with the naphtha and hydrogen, preferably to the initial reactor of the series of reactors of the reforming unit, in concentration ranging from about 100 vppm of hydrogen to about 10,000 vppm of hydrogen, preferably from about 100 vppm to about 5000 vppm of hydrogen.

摘要: A rhenium-containing catalyst, particularly one comprising platinum and rhenium, composited with a porous inorganic support material, especially alumina, is found to be more selective in hydrocarbon conversion reactions, particularly reforming (hydroforming) when pretreated in a sequence which includes the steps of oxidation, dry hydrogen reduction, and sulfiding. In all embodiments, the hydrogen reduction step is conducted at conditions sufficient to remove product water from the catalyst as it is produced until the catalyst becomes dry, or desiccated, and to continue such treatment until the amount of water contained in the exit gas is less than about 1000 ppm, preferably less than about 500 ppm. In a preferred embodiment, the catalyst is desiccated by an initial high temperature oxidation treat to activate the porous inorganic oxide base, or alumina, and then the hydrogen reduction step is performed at a lower temperature than that employed to effect the oxidation.
