Classification: CPC C  B | IPC B  C

Claim 0:
1. A process for operating a reforming reactor system, the process comprising:
operating a first series of reactors, wherein the first series of reactors comprises a plurality of reactors, and wherein each reactor within the plurality of reactors in the first series of reactors contains a catalyst comprising at least one Group VIII metal, a zeolitic support, and at least one halogen and capable of catalyzing the reaction of at least a portion of hydrocarbons in a hydrocarbon feed into aromatic hydrocarbons, thus providing a first reactor series effluent comprising the aromatic hydrocarbons, unreacted hydrocarbons, and hydrogen;
separating hydrogen from the first reactor series effluent, thus providing hydrogen and a reduced-hydrogen first reactor series effluent; and
operating a second series of reactors;
wherein the second series of reactors comprises a plurality of reactors,
wherein each reactor within the plurality of reactors in the second series of reactors contains a catalyst comprising at least one Group VIII metal, a zeolitic support, and at least one halogen capable of converting unreacted hydrocarbons in the reduced-hydrogen first reactor series effluent into the aromatic hydrocarbons, and
wherein a fouling rate of the catalyst in any one of the reactors within the plurality of reactors in the first series of reactors is less than a fouling rate of the catalyst in any one of the reactors within the plurality of reactors in the second series of reactors.
