Beschreibung
Zusammenfassung:	There is provided with a system comprising a carbon dioxide processing unit configured to generate a metal carbonate by reacting a carbon dioxide containing gas with an aqueous dispersion containing a metal hydroxide and acetonitrile, a separation unit configured to separate a dispersion obtained after the carbon dioxide-containing gas is processed to generate a precipitate and a residual liquid, a residual liquid supply unit configured to supply the residual liquid to the carbon dioxide processing unit, a heating unit configured to generate carbon dioxide by thermally decomposing the precipitate, and a graphene generating unit configured to generate graphene by heating the generated carbon dioxide, wherein a content of acetonitrile in an aqueous dispersion supplied together with the residual liquid to the carbon dioxide processing unit is decided based on an amount of acetonitrile in the residual liquid. cm oo 0 +-0 0 co0 U)) LL (D LL Qc'j 0N m oO (N 5--J
