Abstract: ALUMINA. THE SECOND CATALYST MAY CONTAIN ALSO A SMALL AMOUNT OF RHENIUM. THE FIRST REFORMATE SHOULD POSSESS A PARAFFINS-TO-NAPHTHENES RATIO OF AT LEAST 5 TO 1.
A PETROLEUM HYDROCARBON FRACTION IS CONTACTED IN A FIRST REFORMING ZONE WITH A FIRST CATALYST COMPRISING A GROUP VIII NOBLE METAL, A HALIDE, AND ALUMINA TO PRODUCE A FIRST REFORMATE, WHICH IS SUBSEQUENTLY CONTACTED IN A SECOND REFORMING ZONE WITH A SECOND CATALYST COMPRISING THE OXIDES OF CHROMIUM, A MEMBER SELECTED FROM THE GROUP CONSISTING OF AN OXIDE, OF AN ALKALI METAL, AN OXIDE OF AN ALKALINE EARTH METAL, AND MIXTURES THEREOF, AND

Abstract: A novel catalytic composition comprises a Group VIII metal, rhenium, and selenium deposited on a solid catalytic support comprising a refractory inorganic oxide. The preferred Group VIII metal is platinum and the preferred inorganic oxide is catalytically active alumina. This catalyst may be used in a process for reforming petroleum hydrocarbon fractions. The reforming process comprises contacting a petroleum hydrocarbon fraction in a reforming zone under reforming conditions and in the presence of hydrogen with the novel catalyst to obtain high octane blending components. In this process, the catalyst need not receive a sulfur pretreatment either prior to initial operation or after each regeneration of the catalyst. Advantageously, neither sulfiding of the catalyst nor sulfur distribution on the catalyst need be considered.
