  • Patent number: 4791088
    Abstract: Layered silicate materials of high thermal stability and surface area which contain interspathic oxides such as silica as prepared by treating a layered silicate, with organic cation, to spread the layers apart. A compound such as tetraethylorthosilicate, capable of forming said oxide, is thereafter introduced between the layers. The resulting product is treated to form the oxide, e.g. by hydrolysis, to produce the layered silicate material. The resulting product may be employed as a catalyst material in the conversion of hydrocarbons.

  • Patent number: 4752595
    Abstract: A process is described for regenerating a coke and poison deactivated noble metal-containing zeolite catalyst material. The activity of the catalyst after oxygen regeneration can be improved by treating the oxidized catalyst at temperatures from 100.degree. to 250.degree. C. (212.degree.-482.degree. F.) or lower, preferably 100.degree. to 200.degree. C. (212.degree.-392.degree. F.), or most preferably 150.degree. to 200.degree. C. (302.degree.-392.degree. F.), in a reducing atmosphere, as opposed to higher conventional reducing temperatures. The process permits catalyst reactivation by removing coke and other poisons, such as nitrogen, from the catalyst while avoiding excess agglomeration of the noble metals thereon.

  • Patent number: 4747815
    Abstract: The present invention relates to a collection of ultra-thin bags and a collection of bags per se wherein said bags are made by providing two separated thermoplastic films; forming transversely across each separated film, lines of weakness extending from one edge of each film to the other, with each line spaced from the next a bag length distance apart; bringing the films together in face-to-face relationship with the lines of weakness across one film in registration with those of the other films; sealing the films transversely along lines parallel with and immediately adjacent to the lines of weakness; slit-sealing the film layers at one or more bag width intervals to complete individual but interconnected bag structures; and collecting each strip of interconnected bags into a volumetrically efficient form.

  • Patent number: 4744200
    Abstract: A bag pack of a plurality of stacked bags made from thermoplastic film, each bag comprising front and rear walls; a bottom; an open-mouth portion, said open-mouth portion being characterized by having handles which are integral extensions of said walls and located at opposite ends of said bag mouth portion. A single film tab member extends above each rear bag wall and above the open-mouth portion. The tab is coplanar with the rear wall and connected thereto through a localized line of film weakening. The tabs of all bags are in registration and are a collection of only tabs coplanar with said rear walls. The tabs are bonded together and include a suspension means to accommodate physical suspension of the pack.

  • Patent number: 4728439
    Abstract: A method is disclosed for flocculating suspensions containing (a) layered oxide materials intercalated with a hydrophobic swelling agent and (b) nonintercalated hydrophobic swelling agent. The suspension is contacted with a ketone, water, and a cationic organic polymer; the resulting mixture is maintained at a sufficiently alkaline pH to prevent removal of the intercalated swelling agent during the flocculation treatment. This method is particularly useful for preparing swelled layered chalcogenide materials for the introduction of interspathic polymeric chalcogenide precursors in order to form a thermally stable product.

  • Patent number: 4720348
    Abstract: Waterflooding process for the recovery of oil from a subterranean formation in which at least a portion of the injected water is thickened by the addition of a mixture of sulfonated polyethoxylated aliphatic alcohol surfactants. The thickened water has a salinity within the range of 5-18 percent. The mixture of sulfonated polyethoxylated aliphatic alcohols has an HLB within the range of 10.0-14.0 and the lipophilic base of the surfactant mixture contains an average of from 16 to 20 carbon atoms. The surfactant mixture incareases the viscosity of the water to a value greater than viscosity achieved through the addition of only one of the surfactant components.

  • Patent number: 4719189
    Abstract: A process is described for rejuvenating a coke-deactivated noble metal-containing zeolite catalyst material which comprises removing coke from a non-sulfided catalyst by contacting the catalyst with oxygen only in the presence of sulfur dioxide, and thereafter reducing the catalyst in the presence of a reducing agent such as hydrogen. The process permits catalyst reactivation by burning off coke from the catalyst while avoiding excessive agglomeration of the noble metal thereon.

  • Patent number: 4711302
    Abstract: Voids in a gravel pack, particularly in deviated wellbores, are substantially eliminated via a process which utilizes a high energy impulse device. Said device is lowered into the vicinity of the voids and detonated thereby causing turbulence through the screen or slotted liner which causes a re-adjustment of the pack. Energy from said device can be tailored to allow considerable agitation to the gravel pack and screen without destroying said screen.
