    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： 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 upgrading oil feedstock wherein the feedstock is hydrotreated, hydrocracked, and flashed and/or distilled. The bottoms are then vacuum distilled to adjust viscosity and volatility. The refined feed is then extracted, dewaxed, and cascaded to a hydrofinishing step, where it is contacted with a catalyst having a metal hydrogenation function in order to produce lubricant products.

    摘要： A process for upgrading a hydrocarbon oil is provided which comprises introducing the oil and an aromatic extraction solvent containing 0.1 to 10 vol % water into an extraction zone for contact of the oil and solvent therein whereby an extract solution is formed; and injecting water into the extraction zone at a point below that at which the extraction solvent is introduced. The injected water is injected substantially countercurrent to the extraction solvent at a velocity of about 0.5 to 3 ft/sec in an amount ranging from about 0.1 to about 10 LV% based on the amount of extract solution being processed.

    摘要： A process wherein a coked, deactivated iridium-containing catalyst can be reactivated in a sequence of burn steps, inclusive of a low temperature primary burn step and a subsequent high temperature burn step. In (1) the low temperature primary burn step (i) the chloride level of the catalyst is raised and the catalyst passivated by contact with a hydrogen chloride containing gas, (ii) and coke is then burned from the catalyst by contact with a gas which contains hydrogen chloride at level sufficient to suppress iridium agglomeration at a level of oxygen providing burn temperatures which do not exceed about 425.degree. C., this being sufficient to remove a preponderance of the coke without agglomeration of the iridium component. (2) In a high temperature secondary burn step the catalyst is subjected to (iii) a chlorination step wherein the catalyst is contacted with a hydrogen chloride containing gas sufficient to raise the chloride level of the catalyst to a yet higher level for suppression of iridium agglomeration at higher temperature than 425.degree. C., (iv) residual coke is then burned from said catalyst by contact with a gas which contains hydrogen chloride at level sufficient to suppress iridium agglomeration at a level of oxygen sufficient to provide temperatures greater than 425.degree. C., sufficient to burn residual coke from the catalyst without agglomeration of the iridium. The high chloride catalyst can then be (3) stripped with steam, or steam and hydrogen chloride to reduce the level of chloride.
