  • Method for separating gases using a particulate composite material with carbon matrix
    Patent number: 5411577
    Abstract: A method for separating gases wherein the gases to be separated are contacted with a particulate composite material with a carbon matrix to selectively adsorb gases. The material contains a microporous phase which is essentially carbon with a microporous volume between 0.1 cm.sup.2 /g and 1 cm.sup.2 /g, which is associated with an amorphous mineral dispersed phase containing an oxide of silicon, aluminum, titanium or magnesium disposed on the carbon phase at a thickness of less than 10 nm.
    Type: Grant
    Filed: December 22, 1993
    Date of Patent: May 2, 1995
    Assignee: l'Air Liquide, Societe Anonyme Pour l'Etude et l'Exploitation des Procedes Georges Claude
    Inventors: Serge Moreau, Bernard Sardan, Pierre Ehrburger
  • Preparation of particulate composite material with carbon matrix
    Patent number: 5294585
    Abstract: The present invention concerns a polyphase particulate composite material containing a microporous phase which is essentially carbon whose microporous volume is between 0.1 cm.sup.3 /g and 1 cm.sup.3 /g, which is associated with an amorphous mineral dispersed phase essentially consisting of an oxide of silicon, aluminum, titanium or magnesium disposed on the carbon phase, at a thickness of less than 10 nm. The invention is also concerned with a process for the preparation of these composite materials, and the use thereof as a molecular sieve.
