  • Patent number: 9649618
    Abstract: The present invention relates to a method for preparing a solid amine gas adsorption material. The method synthesizes a porous solid amine gas adsorption material that loads organic amine evenly. In the method, a certain amount of acidic gas is introduced while organic amine molecules are introduced into a silicate solution as template agents, which not only makes sizes of SiO2 pore channels homogeneous, but also makes organic amine molecules highly evenly distributed on a surface of SiO2. In addition, the acidic gas protects —NH2 groups of organic amine, and avoids —NH2 adhesion inactivation due to hydrogen bonding during the synthesis process of the material. The present invention also relates to a method for preparing a solid amine gas adsorption material after obtaining a silicate solution from fly ash. The solid amine gas adsorption material prepared has more stable and effective gas adsorption performance.

  • Patent number: 9249934
    Abstract: Adsorbent pellets coated with an outer nano-porous layer can be loaded with gas at loading pressures of 250 bar or greater, enabling a much higher loading than can be achieved at low pressures. The nano-porous layer provides nano-valves which can be sealed with an adsorbate such as ethanol or a hydrocarbon to close the nano-valves. The closed nano-valves maintain the high loading pressure inside the adsorbent pellets, and thus maintain the gas loading, during storage of the loaded nano-valved adsorbent pellets at much lower pressure. To release the gas, the nano-porous layer can be heated to a temperature sufficient to vaporize the adsorbate and open the nano-valves.
