METHOD OF REDUCING DISCHARGED CARBON DIOXIDE

摘要

A method of reducing discharged carbon dioxide, intended to reduce the amount of CO2 discharged into the atmosphere by efficient absorption and removal of the CO2 in exhaust gas produced in industrial processes and the like, characterized by comprising the steps of blowing exhaust gas containing CO2 into an aggregate of solid particles containing CaO and/or Ca(OH)2, for contact therewith, so as to fix the CO2 in the exhaust gas on the solid particles as CaCO3, thereby reducing the CO2 concentration in the exhaust gas, and further characterized in that preferably most of solid particles which contact exhaust gas containing CO2 contain water and more preferably most of solid particles which contact exhaust gas containing CO2 have surface adhering water.
