It is imperative that data be obtained regarding both the composition and leaching properties of combusted liquefaction residues in order to more accurately estimate the long term processing costs of this material. Additionally, a need exists to follow the distribution and effective use of dispersed catalysts during liquefaction, as well as catalyst recovery, recycle and rejection from the system, which are especially important should more expensive catalytic systems be contemplated. Elemental analysis with a high energy charged-particle beam is a powerful analytical tool that has moved out of the realm of the specialized {open_quote}nuclear{close_quote} laboratory and found widespread use amongst researchers in many different areas. We are currently using simultaneous particle-induced X-ray and gamma-ray emission analysis (PIXE/PIGE) to investigate the fate of major, minor and trace metal species during the direct liquefaction of a subbituminous coal. In addition, PIXE/PIGE is being used to follow the fate of these species during the combustion of liquefaction residues.
