IMPROVED INTEGRATED CHEMICAL PROCESS Russian patent published in 2014 - IPC B01D53/62 C01F5/24 C01B31/24 

FIELD: chemistry.

SUBSTANCE: invention relates to the technology of converting carbon dioxide into solid material via mineral carbonisation. The method comprises the following steps: (a) direct thermal activation of magnesium silicate hydroxide mineral feedstock by combustion of fuel to produce an activated feedstock; (b) separation from the activated feedstock of metal oxides at least substantially excluding magnesium oxide and magnesium silicate to produce a residual activated feedstock; (c) before or after said separation step suspension of the activated feedstock in a solvent to form a suspension; and (d) contacting the suspension of residual activated feedstock with carbon dioxide to convert the carbon dioxide into magnesium carbonate.

EFFECT: invention improves the cost-performance ratio and reduces the amount of carbon dioxide emitted into the atmosphere.
