  • Method for producing high-purity electrolyte for vanadium redox flow battery using catalytic reactor
    Patent number: 10978728
    Abstract: The present invention relates to a method for producing a 3- to 3.5-valent vanadium solution from a 4-valent vanadium solution by a catalytic reaction in the presence of a reducing agent, which generates a gas product during oxidation; a method for producing an electrolyte for a vanadium redox flow battery; and an apparatus for producing a liquid electrolyte for a vanadium redox flow battery. The present invention is characterized in that when a 3- to 3.5-valent vanadium electrolyte is produced from a 4-valent vanadium electrolyte by a catalytic reaction in the presence of a reducing agent, which generates a gas product during oxidation, the gas product produced in the catalytic reaction is captured with inert gas bubbles, which are carrier gases, and is removed from the reaction solution of the catalytic reaction by gas-liquid phase separation, thereby accelerating the catalytic reaction towards the forward reaction.

  • Shell-and-tube type reactor for reforming natural gas and a preparation method of syngas or hydrogen gas by using the same
    Patent number: 10632437
    Abstract: The present invention relates to a shell-and-tube type reactor for reforming natural gas and a method for manufacturing syngas or hydrogen gas by using the same. According to the present invention, a shell-and-tube type reactor for reforming natural gas comprises a reaction catalyst for reforming natural gas, which is filled in a reactor shell; at least one tube for separating hydrogen; and a tube for an exothermic reaction or a tube type heat-exchanger for heating, which is disposed at the center of the reactor so as to have excellent operating efficiency and enable production of high-purity hydrogen and collection of carbon dioxide simultaneously along with a reaction.
