  • Publication number: 20160346773
    Abstract: A catalyst composite and a process for preparing the catalyst composite are described. The catalyst composite includes a microporous material having a gallium component dispersed thereon; and a hydroxy metal oxide binder, where the metal is zirconium, titanium, or a mixture thereof. The process includes mixing a gelling agent, water, and the hydroxy metal oxide binder precursor to form a solution. The solution is combined with a microporous material to form a slurry, and the slurry is formed into a shaped article. The article is dried to convert the hydroxy metal oxide binder precursor into a hydroxy metal oxide binder and form the catalyst composite.

  • Publication number: 20130005564
    Abstract: Composites of a crystalline or long-ranged ordered material (CLROM), for example zeolites and non-zeolitic molecular sieves, are disclosed. The composites have both a macroscopic particle size (e.g., an average particle size of greater than about 0.1 mm), as desired in commercial applications, as well as improved functionality. Such composites result from the conversion of a conventional amorphous material, for example a solid amorphous silica alumina of this particle size, into the CLROM. According to particular embodiments, all or substantially all (e.g., at least about 99%) of the amorphous material is converted to the CLROM, such that essentially the entire macroscopic material may have the desired functionality of the CLROM as a catalyst or adsorbent.

  • Patent number: 8343880
    Abstract: A process for forming a zeolite beta dielectric layer onto a substrate such as a silicon wafer has been developed. The zeolite beta is characterized in that it has an aluminum concentration from about 0.1 to about 2.0 wt. %, and has crystallites from about 5 to about 40 nanometers. The process involves first dealuminating a starting zeolite beta, then preparing a slurry of the dealuminated zeolite beta followed by coating a substrate, e.g. silicon wafer with the slurry, heating to form a zeolite beta film and treating the zeolite beta with a silylating agent.

  • Publication number: 20110138999
    Abstract: Metal-organic framework (MOF)-polymer mixed matrix membranes (MOF-MMMs) can be prepared by dispersing high surface area MOFs into a polymer matrix. The MOFs allow the polymer to infiltrate the pores of the MOFs, which improves the interfacial and mechanical properties of the polymer and in turn affects permeability. These mixed matrix membranes are attractive candidates for practical gas separation applications such as CO2 removal from natural gas.

  • Publication number: 20100260664
    Abstract: A process has been developed to synthesize various zeolites with nano size crystals. The process involves forming an aluminosilicate initiator which exhibits the Tyndall effect and contains no appreciable filterable solids. This initiator is then mixed with a clear solution comprising reactive sources of Al, Si, M and R plus water. M is an alkali or alkaline earth metal while R is an organoammonium compound. The resultant reaction mixture is reacted at a temperature and for a time sufficient to produce a zeolite such as zeolite Y with average crystallite size less than 500 nm or preferably less than 300 nm.
