ABSTRACT:
A hydrocarbon conversion process is disclosed wherein a hydrocarbon feed is contacted with a reforming catalyst in the presence of a halogen at conditions which favor dehydrocyclization, isomerization, and dehydroisomerization of the hydrocarbon feed. The degree of the isomerization and dehydroisomerization is controlled by adjusting the amount of halogen present. The amount of halogen present can be adjusted on stream by the addition of halogen-containing gas or water. The reforming catalyst comprises a large-pore zeolite, containing at least one Group VIII metal. In one embodiment, the reforming catalyst comprises: (a) a large-pore zeolite containing barium and platinum; and (b) an acidic or acidifiable inorganic binder selected from the group consisting of silica-alumina, zirconia-silica and alumina.
