  • Patent number: 8889585
    Abstract: A supported tungsten carbide catalyst comprises tungsten carbide as its active component and a mesoporous carbon as its support, wherein tungsten carbide is highly dispersed on the surface and in the channels of the mesoporous carbon, and the content of tungsten element is in the range from 30% to 42% by mass based on the mesoporous carbon. This catalyst can be prepared by impregnation process. This catalyst can be used for the direct catalytic conversion of cellulose to ethylene glycol under the hydrothermal conditions and at a temperature of 245° C. and the hydrogen pressure of 6 MPa with high reactivity, selectivity and stability.

  • Patent number: 8618320
    Abstract: A practical and efficient method for halogenation of activated carbon atoms using readily available N-haloimides and a Lewis acid catalyst has been disclosed. This methodology is applicable to a range of compounds and any halogen atom can be directly introduced to the substrate. The mild reaction conditions, easy workup procedure and simple operation make this method valuable from both an environmental and preparative point of view.
