Abstract： |
The present invention relates to method of fixing CO2 with cinder from refuse incineration, and belongs to the field of greenhouse gas treating technology. The method is to introduce greenhouse gas CO2 into some container holding cinder and capable of vibrating or turning, so that CO2 generates carbonating reaction with small amount of heavy metal and great amount of lime in the cinder containing water in 10-50 % to form stable compound. The reaction time is over 2 hr, and the granularity of the cinder is below 212 micron. The said method can convert CO2 and cinder into harmless matter, has low cost and may realize mechanized operation. |
