    摘要： Improvements in a reforming process for the regeneration and reactivation of a bed of a reforming catalyst, notably an iridium-containing catalyst, coked and catalytically deactivated during the on-oil portion of a reforming cycle. The reactor containing the catalyst is contained in a multi-reactor unit, the individual reactors of which are connected in series via suitable piping and valving. The reactor can be alternately manifolded with production facilities during the on-oil portion of the operating cycle during which period the catalyst of said reactor becomes coked, and can be manifolded alone or with other reactors with a ferrous metal regeneration circuit during the catalyst regeneration and reactivation portion of an operating cycle during which period the catalyst is regenerated and reactivated. In the regeneration and reactivation of the coked catalyst the sequence of process steps include (a) an oxidation step and subsequent reduction step, or (b) a reduction step and subsequent oxidation step, to remove coke and redisperse the iridium component of the catalyst of said reactor. Iron scale carryover from the regeneration circuit to the catalyst of said reactor is drastically reduced by by-passing said reactor during the periods of transition from the (a) oxidation step to the reduction step, or (b) from the reduction step to the oxidation step by closing off the manifold connection between the regeneration circuit and the said reactor. Loss of catalyst activity due to iron scale carryover to the catalyst of said reactor is thus suppressed.

    摘要： A process for reforming a naphtha feed at low severities with tin modified platinum-iridium catalysts. In particular, both high selectivity, and high activity are manifested by such catalysts in reforming a naphtha feed at low severities in the lead reactor, or reactors, of a series of reactors; i.e., within the dehydrogenation and ring isomerization zone, or zones, of a reforming unit. The lead reactors of the series are charged with a tin-containing platinum-iridium catalyst, and the naphtha feed reformed to produce a low RON clear C.sub.5 + liquid reformate. The low octane product of the lead reactors may be transferred to a mogas pool, into blending components, or all or some part of the product further reformed. Preferably, the product is further reformed in a tail reactor, and preferably the tail reactor is charged with a non-tin containing platinum, or platinum-iridium catalyst.

    摘要： A catalytic reforming process in which sulfur moieties are removed from a gaseous product stream by use of a sulfur trap comprised of about 10 to about 70 wt. % nickel dispersed on a support. The sulfur which is removed is both sulfur which is inherent in the feed as well as sulfur which results from presulfiding the catalyst.

    摘要： An alkylation process which utilizes a solid alkylation catalyst is disclosed. The catalyst, which has carbonaceous material adsorbed thereto, is regenerated by reacting the adsorbed carbonaceous material. The reaction step is accomplished by heating the catalyst in the presence of ozone to form an ozonated hydrocarbon, wherein the ozonated hydrocarbon includes carbonyl carbons. The ozonated hydrocarbon is removed by desorbing the carbonyl carbons from the solid alkylation catalyst. The carbonaceous material is preferably reacted at a temperature ranging from about 20.degree. C. to 200.degree. C. The ozone is preferably in a gaseous stream at a concentration ranging from about 1 to 50 volume percent. The carbonyl components are preferably desorbed from the heated alkylation catalyst by sweeping the catalyst with a desorption fluid.

    摘要： Tin modified platinum-iridium catalysts provide high yields of C.sub.5 + liquid reformate in catalytic reforming, concurrent with high activity. In particular, the tin modified platinum-iridium catalysts are of unusually high selectivity, as contrasted with known iridium promoted platinum catalysts. The high selectivity is manifested in reforming a naphtha feed in a reactor charged to capacity with the catalyst, but particularly when used in the dehydrocyclization zone, or tail reactor of a series of reactors, while the lead reactors of the series contain a non tin-containing platinum catalyst, especially a platinum-iridium, or a platinum-rhenium catalyst. The tin modified platinum-iridium catalysts are also highly active, with only moderate loss in the high activity for which iridium stabilized platinum catalysts are known.
