Reforming catalyst system with differentiated acid properties

摘要

A catalyst system comprising a physical mixture of particles of a non-acidic large-pore zeolite containing a platinum-group metal and particles comprising a refractory inorganic oxide which is metal-free is effective for the reforming of a hydrocarbon feedstock. Reforming of paraffinic feedstocks to effect aromatization, particularly of a raffinate from aromatics extraction, provides improved activity in producing gasoline-range products when using the catalyst system of the invention.
