Abstract

In this study, the enrichment of trace elements in two coals under air and oxy-combustion conditions was studied. Twenty-one trace elements were evaluated. The two coal samples had a different concentration for the 21 trace elements, which was due to differences in the maceral composition. Based on the Relative Enrichment (RE) values calculated for the 21 trace elements in this study, 16 of them are non-volatile and the rest (5) are semi-volatile and volatile elements. The non-volatile elements are Li, Cr, V, Mn, Sr, Ba, Cu, Rb, Co, Ni, Ga, Pb, Be, Mo and U. The semi volatile and volatile elements are Ag, Cd, Te, Bi and Ti.
