  • Publication number: 20190184375
    Abstract: A process for preparing a peptized alumina having increased solids and acid contents and a decreased water content. The process comprising mixing a boehmite or pseudoboehmite alumina and acid with a high intensity, high energy mixer at a ratio of 0.16 to 0.65 moles acid/moles alumina for a time period sufficient to form a substantially free-flowing solid particulate having a solids content of 45 to 65 wt %. When used in catalyst manufacture, peptized alumina produced by the process provides an increased rate in catalyst production and decreased costs due to high solids concentration and the presence of less water to be evaporated.

  • Publication number: 20180129491
    Abstract: In one embodiment, a device in a network stores an archive image to a storage location of the device. The archive image comprises a plurality of compressed files. For one or more of the files, the device copies a segment of a particular file in the archive image to a segment copy in the storage location of the device and deletes the segment of particular file from the archive image. The device repeats the copying and deleting steps until the particular file has been fully deleted from the archive image. The device reconstitutes the particular file by merging the segment copy with one or more other segment copies associated with the particular file.

  • Patent number: 9617480
    Abstract: This invention relates to a process of preparing a catalyst from zeolite and peptized alumina. The invention comprises adding a yttrium compound to the zeolite, either prior to, during, or after its combination with the peptized alumina. The yttrium compound can be added to the zeolite via exchange of yttrium onto the zeolite prior to addition of peptized alumina, or the yttrium can be added as a soluble salt during the combination of the zeolite and peptized alumina. In either embodiment, the zeolite catalyst is then formed from the zeolite, yttrium and peptized alumina, optionally containing other inorganic oxide. This invention is suitable for preparing fluid cracking catalysts.
