  • Activated carbons and method for obtaining same from a partly mesophase and partly mesogenic pitch
    Patent number: 7105083
    Abstract: A method for obtaining activated carbons from a partly mesophased and partly mesogenic pitch containing less than about 40% of the a resins, more than about 40% of type ? resins and between about 5 and 30% of type ? resins by activating the pitch preceded by its optional carbonization.

  • Composite material comprising activated carbon and expanded graphite
    Patent number: 6790390
    Abstract: The invention concerns a composite material comprising activated carbon and expanded graphite. The material is a block wherein the activated carbon is homogeneously and uniformly distributed in the form of microporous particles. The texture of said particles is characterised by a microporous volume W0 ranging between 0.1 cm3g−1 and 1.5 cm3g−1 and a mean pore dimension L0 ranging between 2 Å and 30 Å, the activated carbon particles have substantially the same texture wherever they are located in the composite material, the thermal conductivity levels of the material range between 1 and 100 Wm−1K−1. Said material is obtained by heat treatment of a mixture of expanded graphite and an activated carbon precursor in the presence of an activating agent at a temperature and for a time interval sufficient to obtain a wear rate of the activated carbon precursor ranging between 5 and 70% by mass.
