Abstract  

Twenty-two trace elements have been measured by INAA in materials produced in the Solvent Refined Coal (SRC) pilot plant. The elements As, Sb, Se, Hg, Ni, Br, Na, K, Cr, Sc, Fe, Co, Cs, Ce, Rb, Th, Sr, Ba, Tb, Eu, Sm and Lu were measured in coal, SRC, insoluble residues, solvents, and process waters. The liquefaction process produces a fuel lower in toxic trace elements than the parent coal. Elemental balances indicate that except for As, and Hg the SRC and insoluble residues contain more than 80% of the trace elements found in the coal. Evidence is presented indicating significant organic binding of As, Se, Hg, Br, Ni, and Co in the SRC.
