Patent number: 6524372Abstract: A novel compound which can be used in the field of separation and purification of gases is disclosed. The compound can be incorporated into a silica gel incorporating polyazacycloalkane structural units for separating a predetermined gas from a mixture of gases. The mixture of gases is brought into contact with a metallated hybrid gel under conditions which make possible the absorption of the gas to be separated, followed by a phase of desorption of the attached gas, and the recovery of the gas.Type: GrantFiled: July 25, 2000Date of Patent: February 25, 2003Assignee: L′Air Liquide, Societe Anonyme a Directoire et Conseil de Surveillance pour l′Etude et l′Exploitation des Procedes Georges ClaudeInventors: Robert Corriu, Catherine Reye, Ahmad Mehdi, Gérard Dubois, Claude Chuit, Franck Denat, Bruno Roux-Fouillet, Roger Guilard, Gilles Lagrange, Stéphane Brandes
