  • Treating oxidized steels in low-sulfur reforming processes
    Patent number: 5413700
    Abstract: A method for reforming hydrocarbons comprising coating portions of a reactor system with a material more resistant to carburization, reacting the material with metal oxides existing in the portions of the reactor system prior to coating, fixating or removing at least a portion of the oxide in the metal oxides, and reforming hydrocarbons in the reactor system under conditions of low sulfur.
    Type: Grant

    Date of Patent: May 9, 1995
    Assignee: Chevron Research and Technology Company
    Inventors: John V. Heyse, Bernard F. Mulasky
  • Dehydrocyclization or catalytic reforming using sulfur tolerant zeolite catalyst
    Patent number: 5358631
    Abstract: A process is provided for catalytic reforming or dehydrocyclization of hydrocarbons using a catalyst comprising a noble metal, and an intermediate pore size crystalline silicate having a high silica to alumina ratio and a relatively low alkali content. Preferably, the crystalline silicate is in the form of small crystallite size, such as less than 5 microns. The reforming or dehydrocyclization process is sulfur tolerant so that the reforming can be carried out in the presence of sulfur or with periodic exposure to sulfur.
