  • SMALL CRYSTAL LTL FRAMEWORK TYPE ZEOLITES
    Publication number: 20160059225
    Abstract: Small crystal LTL framework type zeolites, characterized as polycrystalline aggregates, each of the aggregates comprising a plurality of spherical or cube-like crystallites and wherein each crystallite has an average crystallite size of from 10 to 50 nm, are disclosed. Such zeolites can be prepared by hydrothermal conversion of FAU framework type zeolites at low H2O/SiO2 mole ratios.

  • INTERZEOLITE TRANSFORMATION AND METAL ENCAPSULATION IN THE ABSENCE OF AN SDA
    Publication number: 20160023913
    Abstract: Provided is a method of encapsulating a metal in a zeolite. The method comprises inserting a metal precursor into a parent zeolite, and then converting the parent zeolite to a zeolite having a higher framework density than the parent zeolite. The conversion is achieved without the need of an organic structure directing agent.

    Publication number: 20160023912
    Abstract: Provided is a method for preparing a zeolite having a Si/Al ratio of at least 10 by interzeolite transformation in the absence of an organic structure directing agent. The method is more cost effective and less equipment intensive as it eliminates the costly organic structure directing agent and the waste treatment at the plant.
