Kinetics of decomposition of CaCo3 in an Australian oil shale

The kinetics of decomposition of calcium carbonate in an Australian (Julia Creek) oil shale were measured because the extent of the carbonate decomposition affects the energy balance for combustors burning either raw or spent shale. The apparent activation energy was similar to that previously reported for the decomposition of calcium carbonate in Colorado oil shale but the Julia Creek shale had rate constants which were smaller than those reported for the Colorado shale.
