Abstract
A substantially water-free hydrocarbon feed is charged to a multiple-reactor reformer system being operated under reforming conditions and comprising at least two reformer reactors serially connected in fluid-flow communication and each containing a reformer catalyst; and, simultaneously with the charging step, a chloriding agent is sequentially introduced, without simultaneously introducing water, immediately upstream from the inlets of all the reformer reactors in an amount and for a period of time that are effective to inhibit the deactivation of the reformer catalyst.
