  • Patent number: 10180253
    Abstract: A carbon dioxide conversion system is provided. The carbon dioxide conversion system includes: an ion transfer membrane that separates oxygen in the air; an oxy-fuel combustor that combusts using oxygen that is separated at the ion transfer membrane as an oxidizing agent; and a dry-reformer that converts carbon dioxide that is generated through an oxy-fuel combustion reaction of the oxy-fuel combustor and methane gas that is supplied from the outside to carbon monoxide and hydrogen by a dry-reforming reaction.
    Type: Grant
    Filed: September 30, 2013
    Date of Patent: January 15, 2019

  • Patent number: 9861932
    Abstract: Disclosed herein is polymer membrane for gas separation or concentration which contains a hybrid nanoporous material, an application thereof, and a manufacturing method thereof. Especially, the hybrid nanoporous material has a window size of 4 ? to 15 ? or has gas adsorption characteristics for a gas to be separated, which is different from those for other gases, and thus the present invention may provide the polymer membrane having improved gas permeation selectivity, an application thereof, and a manufacturing method thereof.
    Type: Grant

  • Patent number: 6958137
    Abstract: The present invention relates to a method for preparing a composite silica membrane with thermal stability by a soaking-rolling method, and more particularly to a method for preparing a composite silica membrane with improved thermal stability by rolling the surface of a porous support with silica xerogel, soaking-rolling the surface with ?-alumina, coating, drying, and sintering the porous support surface, thereby forming a fine coating membrane on the porous support surface.
