Abstract: A reforming catalyst containing a Group VIII metal, or a Group VII B metal, or tin, or germanium, or copper, or selenium or combinations of any two or more metals or oxides thereof is activated by: a) continuously flowing a reducing gas over the catalyst for contact with the catalyst; (b) during step a), flowing a halogen-containing compound over the catalyst for contact with the catalyst for a first time period, wherein the first time period is greater than about 1 minute, and wherein the first time period is less than about 60 minutes; and (c) following step b), and during step a), substantially discontinuing the flow of the halogen-containing compound over the catalyst for a second time period, wherein the second time period is greater than about 1 minute.

Abstract: Catalyst activation of a platinum reforming catalyst system contained in a multiple reactor system by simultaneously reducing the catalyst with a sustained hydrogen flow through the multiple reactor system while introducing a nonmetallic chlorine-containing compound serially into each reactor of the multiple reactor system in an amount to provide from about 0.05 to about 0.3 weight percent chlorine on the catalyst and thereafter purging the system with about 100 to about 50,000 cubic feet of hydrogen per cubic foot of catalyst prior to commencing use of the treated catalyst system for reforming hydrocarbon feed.
