    Abstract: The viscosity index of a hydrocracked lubricating oil stock boiling in the range of about 600*-1100* F. is increased by fractionating the stock into a light fraction boiling from 600* F. to about 750* F. and a bottoms fraction; mildly hydrogenating the light fraction and subsequently reblending the hydrogenated light fraction with the unhydrogenated fraction. Low boiling cracked hydrocarbons may be removed from the reblended lubricating oil to adjust the initial boiling point temperature to a desired value.

    Abstract translation: 通过将原料分馏成沸腾至600°F至约750°F的轻馏分和塔底馏分，将沸点在约600°-1100°F范围内的加氢裂化润滑油原料的粘度指数提高。 轻轻地使轻馏分氢化，随后用未氢化的馏分使氢化轻馏分反应。 低沸点裂化烃可以从再润滑的润滑油中除去，以将初始沸点温度调节至所需值。

    Abstract: THE DISPROPORTIONATION OF MIXTURES OF BRANCHED AND UNBRANCHED DISPROPORTIONATABLE OLEFINS IN THE PRESENCE OR ABSENCE OF ETHYLENE IS IMPROVED BY ADJUSTING THE CONVERSION TO A SPECIFIED LEVEL THEREBY INCREASING THE SELECTIVELY OF THE REACTION TO THE CONVERSION OF THE UNBRANCHED OLEFINS. THE PROCESS HAS PARTICULAR UTILITY IN INCREASING OF THE QUALITY OF OLEFINIC GASOLINE STREAMS IN THAT THE LOWER OCTANE-RATED UNBRANCHED OLEFINS CAN BE SELECTIVELY REMOVED FROM THE GASOLINE BY CONVERSION TO OTHER OLEFINS WHILE SUBSTANTIALLY RETAINING THE HIGHER OCTANE-RATED BRANCHED OLEFINS. IN THIS ASPECT, A PROCESS FOR INCREASING THE OCTANCE VALUE OF OLEFINIC GASOLINE STREAMS IS PROVIDED WHICH COMPRISES THE STEPS OF SEPARATING A C5 FRACTION FROM AN OLEFINIC GASOLINE STREAM, THE C5 FRACTION CONTAINING BOTH PENTENES AND ISOPENTENES, SELECTIVELY DISPROPORTIONATING THE C5 STREAM, WITH OR WITHOUT THE PRESENCE OF ADDED ETHYLENE, TO CONVERT MORE OF THE NORMAL PENTENES THAN THE ISOPENTENES, ALKYLATING THE RESULTING BUTENES AND LIGHTER OLEFINS WITH ISOBUTANE, AND COMBINING THE ALKYLATE AND REMAINING GASOLINE TO PROVIDE A HIGH OCTANE GASOLINE HAVING A REDUCED LIGHT OLEFINS CONTENT. IN A MODIFICATION OF THE ABOVE DESCRIBED MULTISTEP PROCESS PRODUCED PROPYLENE IS DISPROPORTIONATED IN A SECOND OLEFIN DISPROPORTIONATION ZONE, TO PROVIDE ADDITIONAL BUTENES FOR ALKYLATION AND ETHYLENE OR REACTION WITH N-PENTENES IN THE FIRST STEP OF THE PROCESS.

    Abstract: The octane value and volume of gasoline is increased by subjecting an olefinic gasoline to separation to provide a C5 cut containing both linear and branched C5 olefins, reacting the C5 cut with added ethylene in the presence of an olefin disproportionation catalyst to produce isobutene and propylene, disproportionating the produced propylene to provide ethylene and n-butenes, alkylating the n-butenes with isobutane to provide a high octane alkylate, dimerizing produced isobutene to provide diisoburylene, reacting the diisobutylene with ethylene to provide isohexenes, and recombining the high octane alkylate, isohexenes, and the remaining olefinic gasolines to provide an upgraded gasoline having increased octane ratings.

    Abstract: HIGH BOILING HYDROCARBON FEEDS ARE CONVERTED TO HIGH V.I. LUBE OILS IN HIGH YIELDS BY HYDROTREATING IN A FIRST STAGE OVER A HYDROGENATION CATALYST UNDER CONDITIONS ADAPTED TO SATURATE THE POLYNUCLEAR AROMATIC HYDROCARBONS THEREIN AND THEN HYDROCRACKING IN A SECOND STAGE OVER A FAUJASITEBASE CATALYST, SUCH AS PD ON H-FAUJASITE, UNDER CONDITIONS SUCH THAT LESS THAN 15% CONVERSION TO PRODUCTS BOILING BELOW 650*F. OCCURS AND POLYNUCLEAR NAPHTHENES ARE CONVERTED TO SINGLE RING NAPHTHENES, AND PARAFFINS ARE ISOMERIZED TO BRANCH-CHAIN STRUCTURE.
