Elemental analysis of coal using X-ray spectroscopy

An Essay on the Organic Geochemistry of Coal

“…For some reason, concentrations of certain trace elements are unusual (Makjanic et al, 1983). It has the carbon content of a lignite but much less oxygen than a normal lignite, so its distribution of functional groups will be anomalous.…”

Direct microplasma analysis of coals and sorbents for C, H, N, S and mineral element concentrations

“…A range of analytical techniques is generally applied, whether it at transportation links, in commercial service laboratories or at the point of utilization [17]. There has been continuous interest in developing new technologies for real-time elemental analysis [18][19][20][21][22][23][24]. Although control technologies such as sorbents for trapping gaseous emissions are presently employed [25][26][27], power plants would benefit from real time elemental analysis either by blending to satisfy emission constraints at the lowest possible cost or to optimize boiler efficiency based upon timely analysis of the coal being fed to the plant.…”
