| 摘要 |
Disclosed herein is a method of sequestering carbon dioxide produced by a source, comprising: reacting a first cation-based halide, sulfate or nitrate salt or hydrate thereof with water in a first admixture under conditions suitable to form a first product mixture comprising a first step (a) product comprising a first cation-based hydroxide salt, a first cation-based oxide salt and/or a first cation-based hydroxychloride salt and a second step (a) product comprising HCl, H2SO4 or HNO3; admixing some or all of the first step (a) product with a second cation-based halide, sulfate or nitrate salt or hydrate thereof and carbon dioxide produced by the source in a second admixture under conditions suitable to form a second product mixture comprising a first step (b) product comprising a first cation-based halide, sulfate and/or nitrate salt or hydrate thereof, a second step (b) product comprising a second cation-based carbonate salt, and a third step (b) product comprising water; and separating some or all of the second cation-based carbonate salt from the second product mixture, whereby the carbon dioxide is sequestered into a mineral product form. |
