  • Patent number: 9382127
    Abstract: CO2 capture from flue gas is a costly procedure, usually due to the energy required for regeneration of the capture medium. One potential medium which could reduce such an energy consumption, however, is Na2CO3. It has been well studied as a sorbent, and it is understood that the theoretical energy penalty of use of Na2CO3 for CO2 separation is low, due to the relatively low heat of reaction and low heat capacity of the material. While it offers some advantages over other methods, its primary downfall is the slow reaction with CO2 during adsorption and the slow Na2CO3 regeneration process. An aspect of the invention relates to a catalyst to improve reaction kinetics, and more particularly to a catalyst to improve reaction kinetics for CO2 desorption and CO2 adsorption.

  • Patent number: 9382476
    Abstract: The present disclosure relates to a method for preparing a silicate phosphor and the silicate phosphor. The method includes (1) a hydrothermal treatment step of obtaining a layered silicate substituted with a rare-earth metal by hydrothermally treating an aqueous solution as a reaction solution, the solution containing rare-earth metal ions, NaOH and silica, and (2) a calcinating step of forming a crystalline silicate by calcinating the layered silicate substituted with the rare-earth metal. According to the method for preparing the silicate phosphor, the silicate phosphors, which can be used as phosphors for LEDs in the aspects of high covalent character, high luminescent intensity and stability at high temperature, may be prepared by a simplified, economic process. Also, the silicate phosphors may selectively emit red, green or blue light by virtue of the substitution of a silicon position with rare-earth metals of various types.
