Abstract:
A process for activating a platinum-containing reforming catalyst contained in a multiple reaction zone system, said process comprises:(a) reducing said platinum-containing reforming catalyst with hydrogen;(b) simultaneously with step (a) contacting said platinum-containing reforming catalyst with a nonmetallic chlorine-containing compound by introducing said nonmetallic chlorine-containing compound into a reaction zone of said multiple reaction zone system under conditions to effect decomposition of said nonmetallic chlorine-containing compound thereby providing a chlorine-treated catalyst; and(c) thereafter purging said chlorine-treated catalyst with about 100 to about 50,000 cubic feet of hydrogen per cubic foot of said chlorine-treated catalyst prior to using said chlorine-treated catalyst having from about 1.05 to about 1.3 weight percent chlorine, in a reforming process.
