A process for reforming a hydrocarbon stream comprising contacting the hydrocarbon stream in a reforming zone under reforming conditions and in the presence of hydrogen and a hydrocarbon conversion catalyst system comprising a physical particle-form mixture of first and second catalysts, the first catalyst comprising at least one noble metal component and a combined halogen deposed on a high surface area, porous refractory inorganic oxide and being free of a crystalline aluminosilicate component, and the second catalyst being free of a noble metal component and comprising at least one metal component deposed on a solid support comprising a crystalline aluminosilicate material having an alkali metal content of less than about 1 percent of its weight, and being dispersed in a high surface area, porous refractory inorganic oxide; each noble metal component in the first catalyst comprising a noble metal, a compound thereof or a mixture thereof; each metal component in the second catalyst consisting essentially of a member selected from the group consisting of chromium, gallium, germanium, indium, lead, manganese, rhenium, technetium, thallium, tin, tungsten, a compound thereof and a mixture thereof; the weight percent of each noble metal component in the first catalyst, calculated as the noble metal element therein and based on the weight of the first catalyst, being in the range of from about 0.1 to about 1; the weight percent of each combined halogen in the first catalyst, calculated as the halogen element therein and based on the weight of the first catalyst, being in the range of from about 0.1 to about 1; the weight percent of each metal component in the second catalyst, calculated as the metal element therein and based on the weight of the second catalyst, being in the range of from about 0.1 to about 5; the weight percent of crystalline aluminosilicate material in the second catalyst, based on the weight of the second catalyst, being in the range of from about 1 to about 80; and the weight ratio of the first catalyst to the second catalyst being in the range of from about 1:1 to about 10:1.
