Abstract
The invention comprises a method of sequestering carbon dioxide. The method comprises delivering hyaloclastite, a volcanic glass or pumice to a mill capable of reducing the particle size of the hyaloclastite, a volcanic glass or pumice; processing the hyaloclastite, a volcanic glass or pumice in the mill so that the processed hyaloclastite, a volcanic glass or pumice has a volume-based mean particle size of less than or equal to 40 μm; and exposing the hyaloclastite, a volcanic glass or pumice to carbon dioxide in gaseous, liquid or solid form during or after the particle reduction process.
Claims14
A method of mineralizing carbon dioxide comprising:
- providing hyaloclastite wherein the hyaloclastite is basaltic hyaloclastite, intermediate hyaloclastite or combinations or mixtures thereof and wherein the hyaloclastite has a volume-based mean particle size of less than or equal to approximately 40 μm;
- combining the hyaloclastite with a hydraulic cement;
- and
- exposing the hyaloclastite and hydraulic cement to carbon dioxide in gaseous, liquid or solid form, wherein the carbon dioxide in gaseous form is at a concentration greater than its atmospheric concentration.
