Abstract
A process for reforming, with hydrogen, a naphtha in a reforming reactor provided with a rhenium promoted platinum catalyst over which the naphtha is contacted and reacted at reforming conditions to produce a C.sub.5.sup.+ liquid product of improved octane. The catalyst is contacted, on initiation of the reforming reaction, with a maximum of about 75 percent of the rate of hydrogen required for maintaining the optimum C.sub.5.sup.+ liquid yield over the length of the operating cycle. The hydrogen rate is increased not later than the time of line-out of the C.sub.5.sup.+ liquid yield to that required to maintain said optimum C.sub.5.sup.+ liquid yield.
