A systematic study of the effects of maximum retort temperature on trace element distribution during retorting of Sunbury shale was undertaken. Sunbury shale was retorted with maximum temperatures of 500, 600, and 700/sup 0/C. Samples of raw shale, spent shale, oil, and retort water were collected and analyzed by instrumental neutron activation analysis. Results show that >1.0% of As, Se, and Br present in the raw shale have been mobilized into the oil product and retort water. Arsenic moves primarily into the oil product while Se and Br migrate more strongly into the retort water. Other elements for which distributions have been determined to date (Co, Cr, Cs, Fe, Sb, Th, U, and Zn) remain almost entirely in the spent shale after retorting.
