A process for reforming a naphtha feed at low severities with tin modified platinum-iridium catalysts. In particular both high selec-, tivity, and high activity are manifested by such catalysts in reforming a naphtha feed at low severities in the lead reactor or reactors, of a, series of reactors; i.e. within the dehydrogenation and ring isomerization zone, or zones, of a reforming unit. The lead reactors of the series are charged with a tin-containing platinum-iridium catalyst and, the naphtha feed reformed to produce a low RON clear C5+ liquid reformate. The low octane product of the lead reactors may be transferred to a mogas pool, into blending components or all or some part of the …

Why it's free to use
- Filed November 21, 1991. No grant is recorded for it in Canada; had it been granted, its 20-year term would have ended November 21, 2011.
