  • Patent number: 9809454
    Abstract: The present invention is to provide a method for refining hydrogen with a hydrogen refining device in which the inside of a cell is divided into a primary side space and a secondary side space by palladium alloy capillaries each having one end being closed and a tube sheet supporting the open end of the palladium alloy capillaries, in which impurity-containing hydrogen is introduced from the primary side space to allow hydrogen to permeate the palladium alloy capillaries so as to collect pure hydrogen from the secondary side space. The method for refining hydrogen has a capability of decreasing the removed amount of gas containing impurities and efficiently collecting pure hydrogen from the secondary side space. From hydrogen with 1000 ppm or less of impurities as raw material hydrogen, gas containing impurities that does not penetrate the palladium alloy capillaries is removed from the primary side space at the flow rate of 10% or less of the introduction flow rate of the raw material hydrogen.

  • Patent number: 9731247
    Abstract: Highly energy efficient electrodialysis membranes having low operating costs and a novel process for their manufacture are described herein. The membranes are useful in the desalination of water and purification of waste water. They are effective in desalination of seawater due to their low electrical resistance and high permselectivity. These membranes are made by a novel process which results in membranes significantly thinner than prior art commercial electrodialysis membranes. The membranes are produced by polymerizing one or more monofunctional ionogenic monomers with at least one multifunctional monomer in the pores of a porous substrate.
