  • Monolithic catalysts for converting sulfur compounds into SO2
    Patent number: 5278123
    Abstract: Monolithic catalyst shaped articles adopted for the catalytic oxidation conversion of compounds of sulfur, e.g., HS, into sulfur dioxide, include a monolithic substrate containing a catalytically effective amount of at least one catalytically active element for oxidatively converting such compounds of sulfur into SO.sub.2.
    Type: Grant
    Filed: February 19, 1991
    Date of Patent: January 11, 1994
    Assignee: Rhone-Poulenc Chimie
    Inventors: Thierry Chopin, Jean-Luc Hebrard, Eric Quemere
  • Novel catalysts for the treatment of gaseous effluents containing oxidizable sulfur pollutants
    Patent number: 5034369
    Abstract: Novel catalysts for the purification of gaseous effluents containing contaminating amounts of sulfur compounds include a catalytically active phase for the oxidation of such sulfur compounds into elemental sulfur, SO.sub.2 and/or SO.sub.3 and are shaped as to have a ratio between their external surface area and their volume of at least 2 mm.sup.-1 ; advantageously such catalysts have a concave multilobal configuration, preferably trilobal or quadrilobal.
