  • Method for producing coated carbon particles and use of the latter in anode materials for lithium-ion batteries
    Patent number: 8673502
    Abstract: The invention relates to a process for producing coated carbon particles, which comprises coating electrically conductive carbon particles with elemental doped or undoped silicon by chemical vapor deposition from at least one gaseous silane in an oxygen-free gas atmosphere in a reaction space, with the electrically conductive carbon particles being in continual motion during the vapor deposition, and also correspondingly coated carbon particles and their use in anode materials for lithium ion batteries.
    Type: Grant
    Filed: January 25, 2006
    Date of Patent: March 18, 2014
    Assignee: EVONIK DEGUSSA GmbH
    Inventors: Frank-Martin Petrat, Hartmut Wiggers, Burkhard Reeken, Michael Holzapfel, Hilmi Buqa, Petr Novak
  • Method for continuous catalytic hydrogenation
    Patent number: 8586784
    Abstract: The invention relates to the preparation of alicyclic carboxylic acids or their derivatives by selective hydrogenation of the corresponding aromatic carboxylic acid (derivatives) in at least two series-connected reactors, at least one reactor being operated in loop operating mode. The catalyst volumes in the method are set in such a manner that the catalyst volume required, based on the conversion rate, is as low as possible.

  • Method for preparing alicyclic carboxylic acids and their esters
    Patent number: 7435848
    Abstract: A method for the continuous preparation of an alicyclic carboxylic acid or an ester of the alicyclic carboxylic acid. A plastic which incorporates the alicyclic carboxylic acid or an ester of the alicyclic carboxylic acid. An article made of a plastic which incorporates the alicyclic carboxylic acid or an ester of the alicyclic carboxylic acid. A liquid which incorporates the alicycic carboxylic acid or an ester of the alicyclic carboxylic acid.
