Determination of Trace Element Forms in Solvent Refined Coal Productss found to be approximately 76 ppm, thus ruling out U minerals. In SRC I it was established that Ti, V, As, Ga, Fe, Zn, and Se showed distinct organic affinity and that these elements were probably present as metal-organic complexes or complexed in the asphaltene or preasphaltene structure.

Development and Calibration of Standards for PNAA Assay of Coalandards which would be used in future PNAA field systems. This set has to cover a broad range of different types of coals, taking into account physical characteristics and elemental compositions. The present set of standards was calibrated against the sampling and analytical ASTM methods which were

Investigation of Coal Hydrogenation Using Deuterium as an Isotopic Tracervered from the reaction products. The results indicate that not only hydrogen donation but also hydrogen exchange involving the α-positions of tetralin can have a significant role in stabilizing the fragments that form during the thermal decomposition of the coal. In addition, evidence was obtained
