Influence of Ball Milling on CaO Crystal Growth During

Influence of Ball Milling on CaO Crystal Growth During

The multicycle CO2 capture performance of CaO derived from the calcination of ballmilled limestone and dolomite have been tested under high temperature and high CO2 concentration environment for the first time. Here it is shown that the CO2 capture capacity of CaO is inversely related to the milling power applied to the starting mineral and the size of nascent CaO nanocrystals.
