AI Technical Summary

Technical Problem

Current carbon dioxide capture and storage technologies face challenges such as deterioration of absorbent performance due to impurities, high regeneration energy consumption, and contamination issues, particularly in the use of amine-based solutions for removing CO2 from combustion exhaust gases.

Method used

A method involving the production of a carbon dioxide capture and conversion catalyst by pulverizing oxide and metal powders, preparing crystallized synthetic zeolite, and mixing with alkaline solutions to create a stable catalyst that captures and converts CO2 into sodium carbonate or bicarbonate, reducing energy consumption and impurity effects.

Benefits of technology

The catalyst efficiently captures 0.3 to 0.5 kg/h of CO2 per kg, converting it into usable carbon resources like sodium carbonate or bicarbonate, while also serving as a desulfurization agent, with improved capture efficiency and reduced energy usage.

Abstract

The invention relates to a method for producing a catalyst for carbon dioxide retention and conversion capable of removing carbon dioxide and converting it into other useful materials simultaneously by retaining and converting carbon dioxide in flue gases produced during the combustion of fossil fuels into carbon resources, and a carbon dioxide retention and conversion catalyst produced by such method. The carbon dioxide retention and conversion catalyst under the invention can remove carbon dioxide by retaining carbon dioxide in flue gases produced during the combustion of fossil fuels. The retained carbon dioxide can be converted into other useful materials by converting the collected carbon dioxide into sodium carbonate or sodium bicarbonate as carbon resources.
