Try "PAHs were my work". The seal...PAHs in my work? Try "PAHs were my work". The sealants for asphalt driveways differ. The cheap ones are made out of coar tar pitch, which means lots of PAHs. Plasticied sealants are not laden with PAHs.<br /><br />Your reformer story is interesting. Reforming is high energy, very active catalyst processing. That means not only lots of PAHs, the thermodynamic sink of all hydrocarbon chemistry, but lots of variety in those PAHs. If you had done GC or HPLC of the deposit, it would have been extremely complex, akin to coal tar pitch without the heterocyclic analogues.<br /><br />But lots of glowy components. Your deposit ought to have fluoresced bright blue or greenish.John Fetzerhttp://fetzthechemist.wordpress.com/noreply@blogger.com
