Abstract

A multistage process for the reforming of naphtha feeds in the presence of a catalyst comprising a Gp. VIII noble metal on an alumina carrier to produce a gasoline fraction of increase octane number. Specifically, the feed is reacted, in the absence of added or recycled H2, in a plurality of reaction zones through all of which the catalyst particles flow downwardly via gravity flow. The feed is first reacted in the lowermost reaction zone from which deactivated catalyst particles are withdrawn for regeneration. The effluent from this zone is then reacted in the uppermost reaction zone into which fresh or regenerated catalyst particles are introduced, and then finally in one or more subsequent lower reaction zones. The product is recovered from the effluent of the reaction zone immediately above the lowermost zone. Compressive H2 recycle is eliminated and thus significant energy savings are obtd.
