Abstract
Disclosed are a method and a system for recycling carbon dioxide. The method includes chlorinating a calcium-containing silicate and/or a magnesium-containing silicate to obtain a calcium chloride and/or magnesium chloride, mixing the calcium chloride and/or magnesium chloride with ammonia water and carbon dioxide and performing a carbonation reaction to recover the carbon dioxide and convert it into calcium carbonate and/or magnesium carbonate while generating an ammonium chloride solution, and recovering the ammonium chloride solution generated in the carbonation reaction. The ammonium chloride solution after being concentrated or hydrogen chloride generated from a decomposition reaction of the ammonium chloride solution is directly used to chlorinate the calcium-containing silicate and/or the magnesium-containing silicate. The ammonium chloride is used as a catalyst for the entire mineralization of the carbon dioxide, the final product is the calcium carbonate and/or the magnesium carbonate.
