  • Publication number: 20140165356
    Abstract: A cost effective method for reutilizing exiting refinery equipment associated with either a Reformer Unit or Isomerization Unit by converting such units into units and associated processes for hydrodesulfurizing and cracking naphtha feedstocks into light plant gases and chemical feedstocks. These existing Reformer or Isomerization units and processes can be converted into the processes described herein with very little capital expenditures, essentially utilizing almost all of the existing unit equipment, and with little to no major equipment replacements. The processes disclosed herein also effectively reduce the overproduction of naphtha currently experienced in many modern refineries that have resulted from a reduction in overall demand of gasoline products relative to other refinery products.

  • Publication number: 20110275877
    Abstract: The separation of normal paraffins from isoparaffins using rapid cycle pressure swing adsorption. The present invention also relates to an isomerization process wherein normal paraffins are converted to isoparaffins resulting in an effluent stream containing a mixture of normal paraffins and isoparaffins, which effluent stream is sent to a rapid cycle pressure swing adsorption unit to perform the separation of normal paraffins from isoparaffins.

  • Publication number: 20040129605
    Abstract: A method for converting a fixed-bed catalytic reformer unit to a moving-bed unit. The fixed bed reactor is converted to a moving bed reactor that has continuous or intermittent catalyst feeding facilities to allow continuous or intermittent addition of fresh or regenerated catalyst to the catalyst inlet of the moving-bed reactor and continuous or intermittent removal of spent catalyst from the catalyst outlet of the moving-bed reactor. The spent catalyst removed from the reactor is regenerated in a non-integrated regenerator which may be an offsite regenerator, a centrally located on-site regenerator which serves several reforming units or a regenerator shared with a second moving bed unit. The moving-bed reactor, the catalyst feeding facilities and the catalyst recovery facilities are operatively connected between themselves and to existing facilities from the fixed bed unit, such as piping, compression and reformer charge handling and heating.

  • Publication number: 20030136708
    Abstract: A platinum-containing aluminum oxide reforming catalyst is disclosed which is modified by incorporating silica therein. The resulting catalyst is used to reform naphtha yielding a reformate having a higher C5 and aromatic content than that achieved using a similar catalyst which contains no added silica.
