Title:
METHOD AND SYSTEM FOR CAPTURING AND UTILIZING CARBON DIOXIDE
Document Type and Number:
WIPO Patent Application WO/2022/207013
Kind Code:
A1
Abstract:
A method and system for capturing and utilizing carbon dioxide. The method for capturing and utilizing carbon dioxide comprises: using an alkaline solution to capture carbon dioxide in a target component, to obtain an aqueous carbonate-containing solution; performing electrolytic reduction on the aqueous carbonate-containing solution, to obtain an aqueous hydroxide solution, carbon dioxide electrolytic gas, oxygen and hydrogen, and simultaneously adjusting the output ratio of the carbon dioxide electrolytic gas and the hydrogen by controlling the concentration of the aqueous carbonate-containing solution and the electrolysis voltage of the electrolytic reduction process; optionally performing a catalytic reaction on the carbon dioxide electrolytic gas and the hydrogen, to obtain a hydrocarbon compound, which may act as an industrial by-product. The method for capturing and utilizing carbon dioxide can implement carbon dioxide emission reduction, optionally solve the problem of carbon dioxide and hydrogen transportation and utilization, and also obtain an industrial by-product.
