  • Patent number: 8535448
    Abstract: A method of removing a metal protective layer from a surface of a reactor component comprising treating the metal protective layer with one or more chemical removal agents to remove at least a portion of the metal protective layer from the reactor component. A method of removing a metal protective layer from a surface of a reactor component comprising treating the metal protective layer to remove the metal protective layer from the reactor component, and determining a thickness of the reactor component following treatment.
    Type: Grant
    Filed: July 11, 2011
    Date of Patent: September 17, 2013
    Assignee: Chevron Phillips Chemical Company LP

  • Patent number: 8362310
    Abstract: A hydrocarbon aromatization process comprising adding a nitrogenate, an oxygenate, or both to a hydrocarbon stream to produce an enhanced hydrocarbon stream, and contacting the enhanced hydrocarbon stream with an aromatization catalyst, thereby producing an aromatization reactor effluent comprising aromatic hydrocarbons, wherein the catalyst comprises a non-acidic zeolite support, a group VIII metal, and one or more halides. Also disclosed is a hydrocarbon aromatization process comprising monitoring the presence of an oxygenate, a nitrogenate, or both in an aromatization reactor, monitoring at least one process parameter that indicates the activity of the aromatization catalyst, modifying the amount of the oxygenate, the nitrogenate, or both in the aromatization reactor, thereby affecting the parameter.
