Abstract
A process, apparatus, and cyclopropenimine (CPI) material for generating metal carbonates are disclosed. Generating the metal carbonates comprises reacting carbon dioxide (CO2) with CPI. Generating the metal carbonates also comprises forming a reaction mixture comprising water, metal cations, and a product of the reacting.
Claims20
A process, comprising:
- reacting carbon dioxide (CO2) with a material comprising cyclopropenimine (CPI) moieties to form a product;
- and
- generating metal carbonates, wherein the generating comprises forming a reaction mixture comprising an aqueous solution of metal cations and the product.
A process of carbon dioxide (CO2) mineralization, comprising:
- reacting the CO2 with a cyclopropenimine (CPI) material to generate a carbonate source;
- and
- mixing an aqueous solution of metal cations with the carbonate source.
