Possible methods of reducing the fuel and energy requirements in the production of lime were identified. Four basic concepts were explored in pursuit of a viable method to improve the energy efficiency of lime manufacture: (1) enzymatic catalysis; (2) conversion by Lewis acids in protolytic solvents; (3) attrition grinding/frictional calcination; and (4) catalyzed calcination. The concept which proved most encouraging and which appears to be readily adaptable to current practice emerged with the discovery of the Fused Salt catalysts, which can be introduced with pulverized limestone in a furnace process similar to those commercially used today.
