    Abstract

    The calcination of calcium carbonate in a cement or a lime kiln requires approximately two to four times the theoretical quantity of energy predicted from thermodynamic analysis depending upon the type of cement kiln used. The potential for using catalysts to reduce the total energy requirements was explored. It is, of course, impossible to reduce the theoretical energy requirement for the calcination process. Two possible ways considered to reduce this total requirement were (1) to either increase the rate of calcination at a specific temperature or (2) to decrease the temperature of calcination. Several classes of catalysts show promise of doubling the calcination rate (or decreasing the energy requirement by ½).
