Organics in aqueous process streams of a coal conversion bench-scale unit using the hydrocarbonization process: HPLC and GC/MS analysis. [8 refs]
A bench-scale study of the coal hydrocarbonization process is being conducted at Oak Ridge National Laboratory. As part of this study, the organic constituents in the aqueous stream from the product scrubber are being characterized using high-pressure liquid chromatography (HPLC) for separation of the water-soluble organics and gas chromatography--mass spectrometry (GC/MS) for identification of the organics. For example, in one preparative-scale HPLC separation, more than 100 uv-absorbing constituents were detected and separated. Using GC/MS techniques, many of these chromatographic peaks were identified as phenolic compounds such as catechol, methylcatechols, orcinol, and resorcinol. These compounds were quantified at concentrations of 10 to 1000 milligrams/liter. Experimental methodology for HPLC and GC/MS techniques is discussed, and analytical results and possible environmental implications are presented.
