The SEM with EDS and XRD were used to examine the physical and chemical changes in the sorbents during sulfidation. The active metal oxides components were dispersed in the char matrix as nanosize particles resulting in a high reactivity of the sorbents towards H₂S and COS contained in coal gases. Under the conditions in this study, the sorbents can effectively remove H₂S and COS from the simulated coal gases with high efficiency. Sulfur removal is influenced by the level of iron-loading. The presence of Mo along with Fe in the char-supported sorbents can significantly increase the desulfurization efficiency.]]> Sat 24 Mar 2018 07:40:21 AEDT ]]>
