Oh, Jae Seung

The kinetics for the reductive decomposition of calcium sulfate in the presence of carbon monoxide were investigated using thermogravimetric equipment under various conditions of temperature (1050--1200/degree/C) and gas composition (0--7% carbon monoxide, 0--10% sulfur dioxide, and 10--50% carbon dioxide). Pellets reacted at selected conditions were withdrawn from the reaction system at various stages of the reaction and analyzed by x-ray powder diffraction, scanning electron microscopy with electron microprobe, and BET surface area analysis. 52 figs., 11 tabs.
