  • Patent number: 10780424
    Abstract: Disclosed is a supported catalyst for the preparation of vinyl acetate monomer, a process for preparing the supported catalyst in tablet or pellet form, and a catalytic process for the manufacturing vinyl acetate using the supported catalyst. Specifically, it is shown that catalyst performance shows a strong dependence on the crush strength of the tableted or pelletized alumina support used in the process to make the catalyst, and that the crush strength of the catalyst is closely related to the porosity of the support. Catalyst activity and selectivity can be enhanced by tailoring the crush strength of the support.

  • Publication number: 20140031196
    Abstract: To develop a Fenton reaction catalyst that can maintain divalent iron stably for a long period of time, can utilize trivalent iron or metallic iron, which is an inexpensive iron-supplying source, by converting into divalent iron, and is harmless to the human body and the environment, provided is a Fenton reaction catalyst, including, as an active component, a reaction product obtained by mixing a specific reducing organic substance (e.g., ascorbic acid, a polyphenol-containing plant component, or a plant dry distillation liquid component) with an iron-supplying source at a predetermined ratio in the presence of water. Also provided are a sterilization method, a pollutant degradation method, and a luminescence method based on chemiluminescence, which involve using the Fenton reaction catalyst.

  • Patent number: 8618014
    Abstract: Catalyst compositions for use in forming polyurethane products include a gelling catalyst, a trimerization catalyst, and a cure accelerator. The gelling catalyst is a tertiary amine, mono(tertiary amino) urea, bis(tertiary amino) urea, or a combination of any of these. Any known trimerization catalyst may be used. The cure accelerator may be a diol having at least one primary hydroxyl group, and having from five to 17 chain backbone atoms chosen from carbon, oxygen, or both between the hydroxyl groups, provided that at least five of the backbone atoms are carbon. Alternatively or in addition, the cure accelerator may be a polyol having three or more hydroxyl groups, at least two of which are primary, and having molecular weights between 90 g/mole and 400 g/mole. Delayed initiation of the polyurethane-forming reaction and/or reduced demold time for producing the polyurethane part can be obtained by using these catalyst compositions.

  • Publication number: 20130337998
    Abstract: Aqueous and substantially crystalline iron oxide nanoparticle dispersions and processes for making them are disclosed. The nanoparticle size and size distribution width are advantageous for use in a fuel additive for catalytic reduction of soot combustion in diesel particulate filters. Nanoparticles of the aqueous colloid are transferred to a substantially non-polar liquid comprising a carboxylic acid and one or more low-polarity solvents. The transfer is achieved by mixing the aqueous and substantially non-polar materials, forming an emulsion, followed by a phase separation into a substantially metal-free remnant polar phase and a substantially non-polar organic colloid phase. A method for rapid and substantially complete transfer of non-agglomerated nanoparticles to the low polarity phase in the presence of an organic amine, and a rapid phase separation of the substantially non-polar colloid from a remnant aqueous phase, are provided.
