Abstract:

The influence of storage conditions were examined for a tar sample recovered during the co­ gasification of pine and a Polish black coal. Detailed information regarding molecular mass distribution and average mass estimates were measured by size exclusion chromatography and laser desorption mass spectrometry. These techniques revealed the presence of molecules with masses from <200 to >2000 u in these tars. UV­fluorescence spectroscopy provided information on extents of (aromatic) conjugation. Different reactions mechanisms were observed depending whether the tar was stored cold (5°C) or at room temperature.
