Title:
METHOD FOR PURIFYING GAS FORMED BY ELECTROLYSIS, AND ELECTROLYTIC APPARATUS
Document Type and Number:
WIPO Patent Application WO/2020/196835
Kind Code:
A1
Abstract:
The present invention relates to a method for purifying a gas formed by electrolysis, the method comprising a step for electrolyzing an electrolyte supplied into an electrolytic bath having a negative electrode and a positive electrode, and repeatedly performing electrolysis while circulating the electrolyzed electrolyte through an electrolyte circulating tank provided outside of the electrolytic bath, wherein a bag-shaped diaphragm body, which is formed of a specific porous diaphragm material, has an opening in an upper end thereof, has a shape in which the entire side surface and the entire bottom surface thereof are closed, and has a wide permeation area in the entire side surface and the entire bottom surface thereof, is disposed inside the electrolyte circulating tank, whereby electrolysis can be performed while purifying the electrolyte, in which the gas formed by electrolysis is dissolved and gas bubbles of the gas formed by electrolysis co-exist, and the gas formed by electrolysis and generated from the electrolytic bath can be purified.
