  • Patent number: 10584096
    Abstract: Provided herein is a cyclic imide slurry composition and processes for forming and/or using such a composition. The slurry composition comprises solid cyclic imide and organic liquid, such as liquid alkylbenzene, liquid cyclohexane, and/or liquid organic alcohol (such as cyclohexanol). The slurry composition may find particular use in processes in which the cyclic imide serves as an oxidation catalyst (e.g., as a radical initiator). For instance, the slurry composition may be useful in the oxidation of a liquid alkylbenzene such as cyclohexylbenzene to corresponding 1-cyclohexyl-1-phenyl hydroperoxide. Such an oxidation reaction may further be part of an integrated process for the production of phenol and/or cyclohexanone from benzene via hydroalkylation to form cyclohexylbenzene.

  • Publication number: 20190287655
    Abstract: A method for efficiently processing and storing large data sets associated with a multi-stage bioinformatics analysis of genomic data is disclosed. The present method increases the efficiency of the electronic storage of these large data sets by automatically deleting or compressing intermediate data or a portion of output data and compressing input data, where both deletion and compression are based on predetermined characteristics of said data. When necessary, such data can be recovered using generated metadata associated with the data. Doing so, not only improves the storage efficiency of massively large genomic datasets, but also allows for the consistent reproduction of output data with the re-processing of intermediate data based on information stored in metadata.

  • Patent number: 10214486
    Abstract: Disclosed are processes and systems for oxidizing cycloalkylbenzene such as cyclohexylbenzene to make an oxygenate such as a hydroperoxide thereof. A liquid distributor having multiple liquid ingress ports is used for supplying a cycloalkylbenzene-containing liquid into an oxidation reactor in the form of liquid streams forming part of the reaction medium. A gas distributor distributing an O2-containing gas into the reaction medium in the form of gas streams is preferably located below the liquid distributor. Preferably the gas bubbles upwards in the reaction medium. The agitation and mixing provided by the liquid streams, gas streams/bubbles result in sufficient homogeneity of cycloalkylbenzene concentration, cycloalkylbenzene hydroperoxide concentration, dissolved oxygen concentration, and temperature in the liquid phase.

  • Patent number: 10105668
    Abstract: Systems, methods, and apparatus for distribution of oxygen-containing gas within a gas-liquid oxidation reaction are provided herein. The invention is particularly suited for oxidation of liquid-phase organic reactants with oxidizing gas, such as the oxidation of cyclohexylbenzene to cyclohexylbenzene hydroperoxide using an oxygen-containing gas. The oxygen-containing gas is distributed through a gas distributor and into a liquid-phase reaction medium within an oxidation reactor. In some aspects, this achieves a high degree of uniformity of oxygen concentration within the liquid-phase reaction medium. The gas distributor is disposed within a lower portion of the reactor, and may comprise a network of conduits in fluid communication with each other, which are arranged within a plane that is substantially parallel to a bottom surface of the reactor.
