The removal and recovery of trace-metal compounds in complex matrices, such as heavy crude petroleums and shale oils, is a basic problem in the general area of fundamental petroleum chemistry. We are developing innovative methods to remove arsenic compounds from shale oil and vanadium and nickel compounds from heavy crude petroleums. This involves placing ligands onto polymers that will react with the trace-metal compounds present in these matrices. As well, studies directed toward the molecular characterization of the trace-metal compounds in the above-mentioned petroleums allows selective methods to be utilized in the polymer pendant ligand experiments designed to remove these trace-metals. In this annual report, we will demonstrate the use of polymer pendant catechol ligands in removal and recovery studies using arsenic compounds that were characterized in Green River Formation oil shale and its pyrolysis products. In addition, the evaluation of a new ligand for arsenate removal will also be discussed. The molecular characterization of metallo-non-porphyrin compounds of vanadium and nickel in petroleums and their asphaltenes will also be addressed to clearly demonstrate the need to understand these complex mixtures and to use this knowledge for exploration, catalyst poisoning and removal studies that will directly benefit the petroleum industry. 68 references, 17 figures, 7 tables.
