Abstract
An admixture of granular activated carbon (GAC) and bone char (BC) can be effectively employed to decolorize and to deash white cane sugar liquors. Use of this admixture in place of bone char exclusively results in significantly improved decolorization. The GAC/BC admixture can be effectively reactivated at a temperature within the limit of 900.degree. F. to 1200.degree. F.
