Patent ID: 7488404

Claim:
An apparatus for hydrogenating carbon dioxide comprising, in the order as described below: an electrolytic bath containing a caustic alkaline electrolyte comprising zinc oxide; a drive roller for transporting a long strip of copper base plate in upward and downward directions in the electrolytic bath while cathodically electroreducing it therein; drive rollers for pressing the base plate to remove excess amounts of electrolyte contained in porous layers provided on both sides of the base plate migrated beyond an electrolyte surface; first groups of drive rollers for sealing inner spaces; and second groups of drive rollers for reactions, connected to the first groups of drive rollers, for forming inner spaces for mixing carbon dioxide with hydrogen and maintaining the high temperature and sealed conditions by heating, wherein some rollers in the second groups of drive rollers for reaction independently comprise an inlet for carbon dioxide and an outlet for reaction products, the outlet is connected to a cooler and a receiver, and a group of drive rollers is provided for transporting the base plate, which has passed through a group of drive rollers for reactions and then another group of rollers for reactions, to an electrolyte in the electrolytic bath.
