  • Microcrystalline paraffin, method for producing microcrystalline paraffins, and use of the microcrystalline paraffins
    Patent number: 9347007
    Abstract: Microcrystalline paraffin having a consistency in a rage of paste-like to solid, prepared by catalytic hydroisomerization of FT paraffins having a carbon chain length distribution in a range of 20 to 105 at temperatures above 200° C., and being free of aromatic compounds, heterocyclic compounds, and naphthenes.
    Type: Grant
    Filed: May 19, 2003
    Date of Patent: May 24, 2016
    Assignee: SASOL WAX GMBH
    Inventors: Helmuth Schulze-Trautmann, Michael Matthäi, Thorsten Butz, Günter Hildebrand
  • Microcrystalline paraffin
    Patent number: 7875166
    Abstract: The invention relates to a novel and completely synthetic microcrystalline paraffin, said paraffin being obtained in a simple manner and with a high yield by the catalytic hydromerisation of paraffin FT comprising 20 to 105 carbon atoms. Said paraffins can be pasty to solid at room temperature and have a higher percentage of iso-paraffins than n-paraffins. Since they do not contain aromatic compounds they are particularly suitable for use in the pharmaceutical, cosmetic and food industries.
    Type: Grant
    Filed: May 31, 2002
    Date of Patent: January 25, 2011
    Assignees: Sasol Wax International AG, Sasol Wax GmbH
    Inventors: Michael Matthäi, Günter Hildebrand, Helmuth Schulze-Trautmann, Thorsten Butz
  • Bitumen or asphalt for the production of road surfaces, road surfaces, and method for the preparation of bitumen or asphalt
    Patent number: 6913416
    Abstract: Bitumen or asphalt for producing a road topping, whereby the bitumen or asphalt contains a proportion of paraffin obtained by Fischer-Tropsch synthesis (FT paraffin). A road topping with the bitumen and a method for producing a corresponding road topping or roadway covering using the bitumen.
    Type: Grant
    Filed: March 20, 2003
    Date of Patent: July 5, 2005
    Assignee: Schuman Sasol GmbH
    Inventors: Günter Hildebrand, Ferdinand Richter, Michael Matthäi, Bruno Iversen, Klaus-Werner Damm
  • Bitumen or asphalt for producing a road topping, road topping and method for the production of bitumen or asphalt
    Patent number: 6588974
    Abstract: The invention relates to bitumen or asphalt for producing a road topping, whereby said bitumen or asphalt contains a proportion of paraffin obtained by Fischer-Tropsch synthesis (FT paraffin). The invention also relates to a road topping with said bitumen and to a method for producing a corresponding road topping or roadway/covering using said bitumen.
    Type: Grant

  • Heat storage medium
    Patent number: 6227285
    Abstract: A heat storage medium such as paraffin for a latent heat accumulator (cold accumulator), which solidifies while forming crystal structures. In order to achieve improved responsiveness on heat input, the crystal structures are modified by a structure additive preferably in terms of hollow structures, such as e.g. hollow cones.
