Abstract Information :
Hetero-atoms and metals are present at high concentration (% to ppm) in heavy crude oils and high-boiling distillation fractions which are increasingly used as feeds in petroleum industry. Their behavior in refining processes is critically dependent on the chemical forms in which they occur (speciation). The diversity of molecules found in oils has stimulated the development of innovative chromatographic and mass spectrometric approaches to generate "fingerprints" at the molecular level.
This presentation will detail the analytical developments linked to speciation analysis of metals and hetero-atoms in crude oil industry during the last decade. Due to the diversity of molecules in crude oils and their fractions, development of hyphenated techniques between separation techniques and elemental detectors such as inductively coupled plasma mass spectrometry (ICP MS) analyzer has been stimulated. From the determination of few molecules present in light fractions (as for As and Hg) to the necessity of fingerprint approaches in heavy fractions for heteroatoms and metals such as vanadium or nickel. Different kind of instrumental setup (GC, GCxGC, HPLC, GPC, HPTLC/LA with elemental and molecular detectors) and their application will be presented.
Following these examples, the need for supramolecular level information will be discussed and the terms of "metallopetroleomics" and “petrointeractomics” will be introduced.
