  • Patent number: 10464817
    Abstract: EMM-26 is a novel synthetic crystalline material having a single crystalline phase with a unique T-atom connectivity and X-ray diffraction pattern which identify it as a novel material. EMM-26 has a two-dimensional pore system defined by 10-membered rings of tetrahedrally coordinated atoms having pore dimensions of ˜6.3 ?ט3.2 ?. EMM-26 may be prepared with a organic structure directing agent, such as 1,6-bis(N-methylpyrrolidinium) hexane dications and/or 1,6-bis(N-methylpiperidinium) hexane dications. EMM-26 may be used in organic compound conversion and/or sorptive processes.

  • Publication number: 20070154387
    Abstract: The present invention is a method that perturbs the initial crystallization of a material from a less desired phase into a more desired phase. More specifically, the present invention is a method to form a different crystallization of a zeolite, mesoporous material, SAPO4, AlPO4 or porous inorganic oxide after the hydrothermal synthesis has started and a precursor crystalline phase has formed.

  • Patent number: 6299760
    Abstract: A hydrodenitrogenation catalyst is prepared by decomposing a nickel (ammonium) molybdotungstate precursor and sulfiding, either pre-use or in situ, the decomposition product.

  • Patent number: 5036032
    Abstract: Supported catalysts for Fischer-Tropsch processes prepared by contacting a suitable support with a catalyst in the form of a metal salt and depositing the catalyst on the support. Where rim type catalyst are preferred, a molten salt starting material is used. For non-rim type catalyst, such as powdered catalyst, solution salt starting materials may be used. The catalyst is prepared without high temperature calcination of the catalyst before reduction by reducing the salt directly on the support to the metal. During the reduction step, the heating rate is a slow single steady heating rate.
