Abstract
A catalytic reforming process uses a riser reactor with multiple catalyst injection points to obtain high aromatics yields from a naphtha feedstock. Product from the riser reactor typically is discharged into a fluidized-reforming reactor, in which the reforming reaction is completed and catalyst is separated from hydrogen and hydrocarbons. Hydrocarbons from the reactor are separated to recover an aromatized product. Catalyst is regenerated to remove coke and reduced for reuse in the reforming process.
Claims7
A process for the catalytic reforming of a hydrocarbon feedstock comprising charging the hydrocarbon feedstock to a riser reactor at primary reforming conditions, introducing a reforming catalyst comprising sulfided nickel in an amount of about 0.1 to 5 mass-% on an elemental basis and an alumina support and having an average particle size of between about 60 and 80 microns, withdrawing a vapor product from the riser reactor and recovering an aromatized product.
