Outline of Final Research Achievements |
CO2 is found to be adsorbed quickly on mafic silicate minerals by mechanochemical reaction. Varous rocks and minerals were examined for their reactivity with CO2. The silicates were crushed gently in a big ball mill with mixed gas of 10% CO2 and 90% N2. Residual gas was monitored by gas-chromatograph. The 0.03 mol of CO2 in the mill were experimentally found to react in one hour with one mol olivine and/or peridotite. This experiment has done in a separated single type ball mil. If the system will be developed to continuous crushing ball mill system and equipped at near site of certain factory, The CO2 from factory will be able to react with peridotite at that site.
