  • 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

  • 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.

  • Patent number: 6615906
    Abstract: Latent heat body (1) with paraffin-based latent heat storage material accommodated in a carrier material which has holding spaces, wherein the carrier material comprises fibres of an organic plastics material or natural material or of an inorganic material or of textile materials. The carrier material is assembled from individual carrier-material elements by adhesive bonding, capillary-like holding spaces for the latent heat storage material being formed at least between the carrier-material elements. The latent heat storage material is provided with a thickening agent for providing increased viscosity to the heat storage material while in a molten state.
