    摘要: A process wherein in a hydrofining zone, a sulfur- or nitrogen-containing distillate feed, or feed containing both sulfur and nitrogen, is hydrofined at hydrofining conditions sufficient to convert the sulfur and nitrogen to hydrogen sulfide, and ammonia, respectively, the hydrogen sulfide and ammonia are separated from the hydrofined product, and the hydrofined product contacted in a subsequent zone with hydrogen, or a hydrogen-containing gas over a catalyst which contains elemental iron and one or more alkali- or alkaline-earth metals at reaction conditions sufficient to reduce or restore the color of the hydrofined product. Operation in this manner permits hydrofining of the feed at higher severities, for longer periods, than heretofore possible because the adverse quality of the product reaction mixture normally caused by deterioration of the hydrofiner product at such conditions is remediated by treatment of the hydrofined product over the iron catalyst.

    摘要: A process wherein, in a series of reforming zones, or reactors, each of which contains a bed, or beds of catalyst, the catalyst in the rearward most reforming zones is constituted of a high rhenium, platinum rhenium catalyst, viz., a catalyst comprising supported platinum and a relatively high concentration of rhenium relative to the platinum, and preferably the catalyst in the forwardmost reforming zone, or reactor of the series, is constituted of platinum, or platinum and a relatively low concentration of rhenium relative to the platinum. 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: 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.

    摘要: A process for the hydrogenation of aromatic hydrocarbons contained in hydrocarbonaceous oil feed comprising at least about 15 wppm organic nitrogen compounds is provided in which the feed is contacted with hydrogen in a substantially sulfur-free environment in the presence of a catalyst comprising a Group VIII noble metal component, such as palladium, a Y-type crystalline aluminosilicate zeolite and a support such as alumina. When the hydrogenation activity of the catalyst decreases, the partially deactivated catalyst is stripped with hydrogen periodically to increase the hydrogenation activity of the catalyst.

    摘要: A process for simultaneously removing heteroatoms, such as sulfur, from a virgin distillate stream and a light catalytic cyclic stream in two reaction zones in a hydrotreating process unit. One reaction zone will be a low temperature reaction zone and the other will be the high temperature zone. In the low temperature reaction zone, the cracked stream is reacted with a hydrotreating catalyst at a predetermined temperature and in high temperature reaction zone, the virgin distillate stream is reacted with a catalyst which is less reactive than that of the first reaction zone. When catalyst in the high reaction zone is replaced with fresh catalyst the temperature is lowered so that it now becomes the low temperature zone in which the cracked stream is redirected. Correspondingly, the virgin stream is redirected to the other reaction zone whose temperature is now raised and which becomes the high temperature zone and which now contains a catalyst less active than the low temperature reaction zone which now contains the fresher more active catalyst. This cyclic operation is repeated each time fresh catalyst is substituted for spent catalyst.
