Abstract
Carbon dioxide (CO2) sequestering material production methods are provided. Aspects of the methods include increasing the alkalinity and/or ion concentration of an aqueous liquid by contacting the aqueous liquid with a heat-activated, solid mineral source of alkalinity, where the resultant aqueous liquid having increased alkalinity and/or increased ion concentration may then be employed as a CO2 capture liquid, e.g., in the production of CO2 sequestering materials. Also provided are systems configured for carrying out the methods.
Claims15
A method of increasing the alkalinity and/or ion concentration of an aqueous liquid, the method comprising:
- contacting the aqueous liquid with a heat-activated, solid mineral source of alkalinity to increase the alkalinity of the aqueous liquid.
The method according to any of the preceding claims, wherein solid mineral source comprises a particulate composition.
The method according to any of the preceding claims, wherein the heat-activated, solid mineral source of alkalinity comprises a solid mineral source of alkalinity that has been heated to a temperature ranging from 100° C. to 1500° C.
The method according to any of the preceding claims, wherein the aqueous liquid that is contacted with the heat-activated, solid mineral source of alkalinity comprises an aqueous ammonium salt.
The method according to any of the preceding claims, wherein the method is a method of producing a carbon dioxide (CO2) capture liquid.
A system for producing an aqueous ammonia capture liquid, the system comprising:
- (a) a heat activator configured to heat-activate a solid mineral source of alkalinity;
- and
- (b) an extractor configured to contact a heat-activated, solid mineral source of alkalinity received from the heat activator with an aqueous ammonium salt to produce an aqueous ammonia capture liquid.
