  • Synthetically derived illuminating and heating paraffin oil
    Patent number: 8552231
    Abstract: The invention provides synthetically derived distillate kerosene produced by catalytic conversion of Fisher-Tropsch derived light olefins to distillates (COD) and hydrotreating thereof. The kerosene boils in the range of about 170 to 250° C. and includes less than 10% n-paraffins, more than 75% iso-paraffins and less than 1% aromatics.
    Type: Grant
    Filed: April 29, 2010
    Date of Patent: October 8, 2013
    Assignee: The Petroleum Oil and Gas Corporation of South Africa (Pty) Ltd.
    Inventors: Cyril David Knottenbelt, Carl Dunlop, Kholekile Zono, Maxwell Thomas
  • Process for catalytic conversion of Fischer-Tropsch derived olefins to distillates
    Patent number: 8318003
    Abstract: The invention provides a low aromatic producing process for catalytical conversion of Fisher-Tropsch derived olefins to distillates (COD), which process includes the step of contacting Fisher-Tropsch derived olefins with a zeolite type catalyst at pressures of more than 50 barg.

  • Production of Near Zero Aromatics Containing Diesels
    Publication number: 20080250699
    Abstract: The invention provides a process for the production of synthetically derived diesel and diesel produced by the process. The process includes the steps of catalytic conversion of Fisher-Tropsch derived light olefins to distillates (COD) over a zeolite type catalyst at pressures of more than 50 barg, one step hydrotreating the COD product to simultaneously hydrogenate both olefins and aromatics, and collecting a hydrotreated fraction boiling between about 180° C. to 360° C.
