Abstract

A process for operating a reforming reactor system comprising operating a plurality of reactors until at least one reactor is deemed to have an operational issue, wherein each of the plurality of reactors contains a catalyst capable of converting at least a portion of a hydrocarbon stream to aromatic hydrocarbons, isolating the at least one reactor deemed to have the operational issue from a remaining plurality of reactors that continue to operate to convert at least the portion of the hydrocarbon stream to aromatic hydrocarbons while the at least one reactor deemed to have the operational issue is isolated from the plurality of remaining reactors, addressing the operational issues, returning the at least one reactor to the hydrocarbon stream by connecting the reactor to the remaining plurality of reactors, and resuming operations of the reforming reactor system to convert at least the portion of the hydrocarbon stream to aromatic hydrocarbons.
