Abstract
A reforming process is disclosed which comprises contacting a sulfur-containing hydrocarbon material in at least one scavenging or sulfur removal zone with at least one manganese-containing composition at conditions to remove at least a portion of said sulfur from said hydrocarbon material to produce a hydrocarbon feedstock having a reduced concentration of sulfur; and contacting said hydrocarbon feedstock with a catalyst comprising, optionally, a major amount of a porous solid support, a minor catalytically effective amount of at least one platinum-group metal component, optionally, a minor catalytically effective amount of at least one halogen component, and optionally, at least one rhenium component in the presence of hydrogen at hydrocarbon reforming conditions to obtain a hydrocarbon reformate product.
Claims22
A reforming process for a hydrocarbon material containing a sulfur component comprises:
- contacting in a fixed bed sulfur removal zone at sulfur removal conditions, said hydrocarbon material with a manganese-containing composition which comprises a manganese component cabable of removing at least a portion of said sulfur component at said sulfur removal conditions to produce a reduced sulfur-containing hydrocarbon feedstock, and contacting in a reforming zone in the presence of hydrogen at hydrocarbon reforming conditions said feedstock with a catalyst comprising a minor catalytically effective amount of a platinum-group metal component and a minor catalytically effective amount of a halogen component capable of reforming said feedstock at such reforming conditions to produce a reformed product.
