  • Bridged clays of improved thermal stability process for their preparation and utilization as catalysts
    Patent number: 4753909
    Abstract: There are provided clays of laminated structure bridged by metallic oxides selected from oxides of aluminum and zirconium and containing from 10 to 50% and preferably from 20 to 40% of an oxide of the metal of the group of the lanthanides, preferably of cerium. The presence of cerium improves the thermal resistance during a dry calcination or even under humid air. The clays can be used as catalysts during the conversion of hydrocarbons.
