Abstract:
1. A process for catalytic reforming a naphtha feed stream containing sulfur-compound poisons for a reforming catalyst comprising steps: 1) sending said feed stream through a sulfur guard bed to remove said sulfur compounds from the naphtha feed stream to produce a naphtha stream having a reduced sulfur content, wherein said sulfur guard bed comprises sorbents comprising CuO supported on an alumina substrate and about 0.001 to 2.5% by weight of a chloride additive, wherein said sulfur sorbents are prepared by steps: i) mixing basic copper carbonates CuCO ii) adding NaCl or KCl to the beads of step (i); iii) activating the beads of step (ii) by heat treating at a temperature ranging from 280 to 500° C. to form said sorbent used for step (1); and 2) reforming said naphtha stream having a reduced sulfur content of step (1) in the presence of said reforming catalyst to produce a reformed product.
