Description:
The paper gives results of the characterization of a solid sorbent with crystallite size and strain data from x-ray diffraction line broadening, as part of an EPA investigation of the injection of dry Ca(OH)2 into coal-fired electric power plant burners for the control of SO2 emissions. For the study, seven Ca(OH)2 sorbent materials were evaluated for percent conversion in an isothermal flow reactor operating at 1000 C with 0.3% SO2 and 1 sec residence time. Study results indicated that reactivity was directly proportional to the RMS strain at average column length and to the RMS strain at the column length of maximum frequency of occurrence. The reactivity was seen to be inversely proportional to the crystallite column dimensions.
