Title: Solvent refined coal (SRC) process: trace elements research and development report no. 53, interim report no. 34. Volume III. Pilot plant development work part 6: the fate of trace elements in the SRC process for the period, August 1, 1977 - February 28, 1979. [36 elements]

Abstract

This work reports the results of neutron activation analysis determination of the fate of trace elements in the SRC II process. Six coals were studied for their behavior in material balance runs carried out at the Fort Lewis Pilot Plant. The distribution of trace elements among products and input streams was determined by thermal neutron activation analysis using thermal neutron flux of 8 x 10/sup 12/ neutrons cm/sup -2/ sec/sup -1/ followed by Ge(Li) gamma ray spectroscopy. National Bureau of Standards Standard Reference Materials (SRM) were used to evaluate the analytical precision and accuracy of the methods used. For each material balance study the trace element input stream was taken as ground coal and the output streams were vacuum bottoms, SRC II product oil, and process water. In addition to these major components, oils, sludges and waters from liquid-liquid separators, effluent waters, biosludges, and by-product sulfur were also analyzed. Concerning the distribution of trace elements in the SRC II process, it was found that the vacuum bottoms was the major sink for all trace element studied, with the exception of Hg. Much lower trace element concentrations (except for Hg) were found in the SRC II product oil relative to themore » vacuum bottoms or the feed coal, irrespective of coal type. The results indicate excellent balances for the elements studied, except for Hg. Except for Hg, Se, and C1, the SRC II product and process waters contributed less than 1% of the elemental balances for light oil fractions and process waters indicates that Hg, and to a lesser degree As, Se, and Sb, exhibited volatile behavior in the SRC II process but that the degree of volatility is strongly dependent on conditions or coal type.« less
