    摘要: A process wherein, in a series of reforming zones, employing one or a series of reactors, each of which contains a bed, or beds of catalyst, the catalyst in the rearward most reforming zones is constituted of supported platinum and a relatively high concentration of rhenium, and the catalyst in the forward most reforming zone is constituted of platinum, or platinum and a relatively low concentration of a promoter metal, especially rhenium. In the rearward reaction zones, at least 40 percent, and preferably from 40 percent to about 90 percent, based on the total weight of catalyst in the reactor, or reactors of the unit, is constituted of a rhenium promoted platinum catalyst, the weight ratio of rhenium:plantinum of which at least about 1.5:1, a preferably 2:1, or greater. The beds of catalyst are contacted with a hydrocarbon or naphtha feed, and hydrogen, at reforming conditions to produce a hydrocarbon, or naphtha product of improved octane, and the product is withdrawn.

    摘要: 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.

At least 30 percent, preferably from 40 percent to about 90 percent, of the rearward most reactors of the unit, or even 100 percent, based on the total weight of the catalyst in all of the reactors of the unit, contain a high rhenium, platinum rhenium catalyst, the weight ratio of rhenium:platinum being at least about 1.5:1. The beds of catalyst are contacted with a hydrocarbon or naphtha feed, and hydrogen, and the reaction continued for a period of at least 700 hours, preferably from about 700 hours to about 2750 hours, while conducting the reaction at temperatures ranging from about 850.degree. F. to about 950.degree. F. (E.I.T.), at pressures ranging from about 150 psig to about 350 psig, and at gas rates ranging from about 2500 SCF/B to about 4500 SCF/B.

    摘要: The octane number of a cracked naphtha can be significantly improved in a catalytic cracking unit, without significant decrease in naphtha yield, by maintaining certain critical concentrations of metals on the catalyst, suitably by blending or adding a heavy metals-containing component to the gas oil feed. Suitably, in a catalytic cracking process unit wherein a gas oil feed is cracked in a cracking reactor (zone) at an elevated temperature in the presence of a cracking catalyst, the cracking catalyst is regenerated in a regenerator (regeneration zone) by burning coke off the catalyst, and catalyst is circulated between the reactor and regenerator, sufficient of a metals-containing heavy feedstock is admixed, intermittantly or continuously, with the gas oil feed to deposit metals on said catalyst and raise the metals-content of said catalyst to a level of from about 1500 to about 6000 parts per million, preferably from about 2500 to about 4000 parts per million expressed as equivalent nickel, based on the weight of the catalyst, and said metals level is maintained on the catalyst throughout the operation by withdrawing high metals-containing catalyst and adding low metals-containing catalyst to the regenerator.
