  • Patent number: 10604679
    Abstract: The present disclosure relates to a ski wax composition including superhydrophobic carbon nano particles (CNPs) and a preparation method thereof, and more particularly, to a ski wax composition including a wax and superhydrophobic CNPs and a preparation method thereof. According to the present invention, since the hydrophobicity and retention capacity of the wax can be increased, friction reducing performance of a ski wax can be increased on an ice surface or a snow surface. In addition, since the superhydrophobic CNPs, which can be easily prepared, are used, the productivity of the ski wax composition can be improved and superb friction reducing performance can be exhibited. Further, since the superhydrophobic CNPs are dispersed into the wax by a simple sonication process, a problem caused by adding a surfactant can be solved. Therefore, the ski wax composition according to the present disclosure can be widely applied to industrial fields associated with the winter sports, including skiing.

  • Patent number: 10577243
    Abstract: A reforming catalyst with improved surface area is provided by using high surface area alumina doped with a stabilizer metal as a catalyst support. The surface area of the catalyst can be higher than a typical reforming catalyst, and the surface area can also be maintained under high temperature operation. This can allow use of the catalyst for reforming in a higher temperature environment while maintaining a higher surface area, which can allow for improved dispersion and/or activity of an active metal such as rhodium on the catalyst support. The catalyst can be suitable for production of syngas from natural gas or other hydrocarbon-containing feeds.
