Abstract: An improved catalyst is disclosed for the conversion of hydrocarbons. The catalyst comprises an alumina support, a Friedel-Crafts metal halide, and a platinum-group metal component, wherein the support comprises primarily eta alumina and a small amount of gamma alumina and has a defined pore-size and acidity characteristics. An isomerization process also is disclosed which is particularly effective for the conversion of C4-C7 alkanes.

Abstract: A catalytic reforming process comprises a prereactor which provides an intermediate stream to 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-bed 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.
