A method for monitoring the presence of elemental and organic sulfur compounds in distillable low-rank coal liquefaction products utilizing column chromatography and dual detection (FID/FPD) capillary GC has been developed. The addition of H/sub 2/S to the continuous processing of Beulah, ND lignite does not increase the amount or variety of sulfur-containing organic compounds in the recycle slurry ASTM-D1160 vacuum distillate products. It does, however, introduce sulfur and a variety of volatile sulfur-containing organics into the light oils condensed from the vapor phase in the reactor. The presence and variety of sulfur compounds after 12 to 14 reactor passes reflect the introduction of these components on the startup solvent. No increased mutagenicity was observed with the coal liquids processed with H/sub 2/S. The production of H-donors in the recycle slurry ASTM D-1160 distillates was enhanced by the presence of H/sub 2/S.
