Abstract

In terms of analyzing and modeling conditioned dry
absorption, an unbiased view on the injected hydrated lime particles is
needed. Multiple investigations on the reaction mechanisms are reported in
the literature. Nevertheless, outstanding issues still exist as a necessary
conservation in the time between the particle sampling and analysis as well as
the suitability of the analyzing methods itself has been regarded only roughly
yet. Thus, in this work TGA, XRD, and SEM-EDS were used for analyzing
Ca(OH)2-CaCl2·2H2O-mixtures. TGA turned out to be inappropriate as the
composition of the mixture changes during analysis. A cooling of the particle
samples down to 277.15 K under air exclusion proved to be a sufficient
conservation method for the time span between sampling and analysis.
