  • Patent number: 8021642
    Abstract: A porous crystalline composition having a molar composition as follows: YO2:m X2O3:n ZO, wherein Y is a tetravalent element selected from the group consisting of silicon, germanium, tin, titanium and combinations thereof, X is a trivalent element selected from the group consisting of aluminum, gallium, boron, iron and combinations thereof, Z is a divalent element selected from the group consisting of magnesium, zinc, cobalt, manganese, nickel and combinations thereof, m is between about 0 and about 0.5, n is between about 0 and about 0.5; and the composition has an x-ray diffraction pattern which distinguishes it from the materials. A process for making the composition, and a process using the composition to treat an organic compound are also provided.

  • Publication number: 20050261122
    Abstract: A method for preparing a modified kaolin clay, includes the steps of providing a kaolin clay material having a starting ratio of silica to alumina; mixing the kaolin clay material with acid so as to form a substantially homogenous paste; calcining the paste so as to provide a calcined acid-treated clay material; mixing the calcined acid-treated clay material in water so as to form a suspension; precipitating aluminum from the suspension so as to produce a reduced aluminum suspension; and obtaining a modified clay material from the reduced aluminum suspension, wherein the modified clay material has a final ratio of silica to alumina which is higher than the starting ratio.
