Metal coordination chemistry: removal and recovery of metal compounds from heavy crude and shale oils with multidentate ligands. Annual report, October 1981-October 1982

Technical Report ·
OSTI ID:5896376

The separation and identification by HPLC-GFAA analysis of organic and organoarsenic compounds occurring in oil shale retort and process waters, shale oils and Green River Formation oil shale are described in this report. The molecular characterization of these compounds has given new insight into developing innovative methods for their removal from oil shale retorting products. Catechol (1,2-dihydrocylbenzene) derivatives of both inorganic and organoarsenic compounds may in fact provide the means by which these compounds can be successfully removed from the above mentioned retort products. In addition to model compounds experiments with catechols and characterized inorganic arsenic and organoarsenic compounds, we have also synthesized a polymer that was modified with catechol and are in the process of determining its reactivity with the characterized arsenic compounds. Progress in preparing these catechol-bonded polymers is discussed. In a complimentary study, we have performed molecular characterizations and profile identifications of vanadyl porphyrin and non-porphyrin complexes in various heavy crude petroleums and their asphaltenes by HPLC-GFAA analysis. Results are discussed. (DMC)
