Provided is a process for catalytic reforming a hydrocarbon feedstock containing at least 20 ppbw sulfur. The process comprises passing the hydrocarbon feedstock through at least two serially connected reforming zones, with each zone containing a highly sulfur sensitive reforming catalyst. The catalyst in the first reforming zone is mo re frequently regenerated than the catalyst in the second reforming zone. The result is a highly efficient and simplified process for reforming a sulfur contaminated hydrocarbon feedstock. The process basically employs a minor portion of the highly sulfur sensitive reforming catalyst as both the reforming catalyst and a sulfur removal agent.
