Process for sequestration of carbon dioxide

摘要

The present invention provides a process for sequestration of carbon dioxide comprising:
a. providing a silicate hydroxide mineral comprising lizardite; and
b. subjecting the silicate hydroxide mineral comprising lizardite to a heat treatment to obtain an activated mineral;
c. contacting a carbon dioxide-comprising gas stream with an aqueous slurry comprising the activated mineral to obtain an aqueous magnesium bicarbonate solution and/or magnesium carbonate,
wherein the lizardite comprises lizardite having a crystal structure 1T.
