  • Molecular sieve layers and processes for their manufacture
    Publication number: 20060252631
    Abstract: Layers comprising a molecular sieve layer on a porous or non-porous support, having uniform properties and allowing high flux are prepared from colloidal solutions of zeolite or other molecular sieve precursors (particle size less than 100 nm), by deposition, e.g., by spin or dip-coating, or by in situ crystallization.
    Type: Application
    Filed: April 13, 2006
    Publication date: November 9, 2006
    Inventors: Harry Deckman, Jannetje van den Berge, Allan Jacobson, James McHenry, Klaas Keizer, Zeger Alexander Vroon, Lothar Czarnetzki, Frank Lai, Antonie Bons, Anthonie Burggraaf, Johannes Verduijn, Edward Corcoran, Wilfred Mortier

  • Coated zeolite catalysts and use for hydrocarbon conversion
    Publication number: 20060011514
    Abstract: There is provided a coated zeolite catalyst in which the accessibility of the acid sites on the external surfaces of the zeolite is controlled and a process for converting hydrocarbons utilizing the coated zeolite catalyst. The zeolite catalyst comprises core crystals of a first zeolite and a discontinuous layer of smaller size second crystals of a second zeolite which cover at least a portion of the external surface of the first crystals The coated zeolite catalyst finds particular application in hydrocarbon conversion processes where catalyst activity in combination with zeolite structure are important for reaction selectivity, e.g., catalytic cracking, alkylation, disproportional of toluene, isomerization, and transalkylation reactions.
