Abstract:
1. A reforming process comprising: a. contacting a naphtha boiling range feedstock in a penultimate stage of a multi-stage reforming process at a first reforming pressure with a first reforming catalyst to produce a penultimate effluent; b. separating at least a portion of the penultimate effluent into at least an intermediate reformate comprising at least 70 vol % C c. contacting the intermediate reformate in a final stage of the multi-stage reforming process at a second reforming pressure with a second reforming catalyst to produce a final effluent comprising a final reformate, wherein the final reformate has a target RON that is higher than the intermediate reformate; d. regenerating the final stage catalyst while reforming is taking place in the penultimate stage; and e. temporarily increasing the severity of the penultimate stage to meet the RON target for the product reformate while the final stage catalyst is being regenerated.
