Abstract: The invention provides a process for the catalytic reforming of hydrocarbons comprising contacting the hydrocarbon feed in two or more sequential catalyst zones. The initial catalyst zone is a fixed-bed system and contains an initial catalytic composition comprising a platinum component, a germanium or rhenium component, a refractory inorganic oxide, potassium and a halogen component and then there is a terminal catalyst zone with a terminal catalyst composition that has a similar composition but with an essential lack of potassium. The addition of potassium was found to improve the yield of C5+ hydrocarbons.
