  • Patent number: 9737886
    Abstract: Disclosed herein is a process and an apparatus for producing coated catalysts. A process of the present disclosure includes providing a composition containing a liquid and a catalytically active material and/or a precursor thereof in a stock vessel, providing a support material in a vessel which is rotatable about a longitudinal axis, transporting the composition from the stock vessel through a first conduit to a spray nozzle, transporting a propellant fluid through a second conduit to the spray nozzle, atomizing the composition and propellant fluid in the nozzle to produce an aerosol that flows into the vessel and impregnates the support material present therein, heating the vessel so the liquid present in the aerosol evaporates from the support material and the finely divided support material which has been treated with catalytically active material and/or a precursor thereof is dried, and discharging the vaporized liquid from the vessel.
    Type: Grant

  • Patent number: 8642811
    Abstract: The invention provides a method to produce primary diamines by catalytic conversion of diols having a linear main chain of from 4 to 31 carbon atoms into the corresponding diamines. The reaction is conducted in a liquid or supercritical phase and is catalyzed by a homogeneous ruthenium-containing complex. The primary diamines obtained may be suitable for polyamide syntheses.

  • Patent number: 8604227
    Abstract: The invention provides a process for preparing linear alpha,omega-dicarboxylic diesters by reacting a triglyceride containing fatty acid residues having monounsaturated or polyunsaturated carbon chains with carbon monoxide, an acid and an OH-group donor in one reaction step in the presence of a catalyst.
