ABSTRACT:
An apparatus and method for improving the properties of carbon-containing fly ash through ozonation is described. The apparatus includes a chamber for containing the fly ash and an ozonator that generates an ozone-containing gas. The ozonator supplies the ozone-containing gas such that it enters the chamber with the fly ash and deactivates carbon within the fly ash. Afterwards, the fly ash will have decreased surfactant adsorptivity so that it can be effectively mixed with cement or whatever other materials may require fly ash with passivated carbon.
