Abstract: The pervaporative treatment of hydrocarbon feeds which have been exposed to air or oxygen and which contain mixtures of aromatic and non-aromatic hydrocarbons to selectively separate the feed into an aromatics rich stream and a non-aromatics rich stream is improved by the step of pretreating the hydrocarbon feed over an adsorbent such as attapulgite clay.

Abstract: One embodiment of the present invention is directed to polysubstituted fullerene moieties having a plurality of substituents thereon, selected from the group consisting of hydroxy, oxide, nitro, amino, organocarboxy, amide, and mixtures thereof.Another embodiment is directed toward the preparation of the novel polysubstituted fullerenes. The method of forming polysubstituted fullerenes comprises contacting fullerenes with an electrophilic reagent such as nitronium ion or an organic peracid. When the electrophilic agent is nitronium ion, the fullerene is further contacted with a nucleophilic reagent. Polysubstituted fullerenes comprise a fullerene moiety selected from fullerenes or mixtures thereof having a plurality of substituents thereon.The polysubstituted fullerenes are particularly useful as cross-linking agents in polymers and/or as core building blocks of star polymers.

Abstract: The uniform distribution of mixed phase fluid stream on to the top of a contact bed in a reactor chamber is provided by a horizontal tray with a plurality of spaced-apart, vertically disposed chimneys extending through the tray. These chimneys have a first end to receive liquid and gas above the tray and a second end for distributing the liquid and gas downwardly below the tray. Importantly, the second end is provided with a spray generating device located below the tray for producing a conical downward spray of the mixed fluid phase onto the top surface of a bed of contact material positioned below the tray. The spray generating devices for producing the conical spray are located at positions so that the spray of the mixed fluid stream from one spray generating device as it impinges on the top surface of the fixed bed, will overlap the spray from an adjacent spray generating device.

Abstract: The present invention relates to enhanced process for converting certain ethers, such as sec-butyl ether and isopropyl ether to their corresponding reaction products in the presence of water. This may be accomplished by adding a rate enhancing surfactant, such as an anionic or cationic surfactant to a mixture of the ether and water, preferably least about 10.sup.-5 molar surfactant. Under those conditions the reaction shows an increase in reaction rate over the rate of the process wherein surfactant is not used.

Abstract: Batch auto-refrigerative dewaxing processes employing at least two batch chilling vessels can be improved by integrating the batch auto-refrigerative dewaxing chilling cycles of the chilling vessels so as to have their cycles of operation overlap and use thermocompressors to recover the energy of the hot, high pressure cycle stream of one vessel by operation on the cooler, low pressure cycle stream of the other vessel to increase the pressure of said low pressure cycle stream. The overlap operation of the multiple batch chillers integrated through the thermocompressor will also permit running the cool, low pressure cycle to a pressure even lower than atmospheric without inleakage of air because of the vacuum effect generated by the hot, higher pressure stream running through the thermocompressor. Autorefrigerative dewaxing employs liquified normally gaseous solvents as the chilling solvents such as C.sub.3 -C.sub.4 alkanes/alkenes e.g. propane, propylene, butane, butylene and mixtures thereof.

Abstract: The incremental solvent dilution chilling of 600N waxy oils in a staged agitated chilling tower using cold solvent injection is improved in terms of feed filter rate with respect to a 600N waxy oil having a final boiling point of >600.degree. C. and a mean boiling point of about 500.degree. C. when the solvent dewaxing process is practiced under conditions of cold solvent injection such that there is an equal chilling rate/stage profile as compared to an equal temperature drop/stage profile in the chilling tower and with respect to a 600N waxy oil having a final boiling point of 600.degree. C. and a mean boiling point of about 500.degree. C. when the solvent dewaxing process is practiced under conditions of cold solvent injection such that there is an equal temperature drop/stage profile as compared to an equal chilling rate/stage profile in the chilling tower.

Abstract: It has now been discovered that the hydrogenation of unsaturated homo and copolymers can be effectively carried out in the absence of added gaseous hydrogen by contacting the unsaturated polymer with a hydrogen donor compound in the presence of a Group VIII metal catalyst, especially a supported palladium catalyst, for a time and at a temperature sufficient to bring about the hydrogenation of the unsaturated polymer.

Abstract: Zeolite L with flat basal planes, and reduced crystallite size is prepared in a synthesis modified by the addition of small amounts of additional metal such as magnesium, calcium, barium, cobalt, zinc, chromium, manganese or nickel. The addition of these metals also suppresses unwanted zeolite W formation even when the synthesis would otherwise form this zeolite.

Abstract: This invention relates to a catalytic process for converting a carbonaceous material to a liquid product. More specifically, this invention relates to a process for hydroconverting coal in a hydroconverting zone to liquid hydrocarbon products in the presence of a catalyst prepared in situ, with the catalyst being added to a mixture of coal and solvent as an oil soluble metal compound. An increased quantity of liquid product is achieved by incorporating a hydrocracking zone into the process.
