Abstract : Spent carbon from the carbon-in-pulp (CIP) process was reactivated using 2450 and 915 MHz microwave energy. Dry and wet carbon was used in the tests. Reactivation temperature and dwell periods were varied to determine optimum reactivation and energy consumption. The results indicate that the important properties of microwave-reactivated carbon am superior to those of conventionally reactivated carbon. Microwave heating at 915 MHz is preferred for this application because of its higher electrical efficiency and greater penetration depth compared to 2450 MHz.
