Abstract Content

Increasingly complex processes are used in refineries and petrochemical plants to transform heavier and unconventional oils into various products: ultrapure gases leading to technically advanced polymers, cleaner fuels, lubricants, bitumen… In order to optimize these (catalytic) processes, oils and hydrocarbon cuts have to be described at the molecular level. The origin of several polymer properties and efficiency of additives in polymers can be studied through their molecular characterization.[1,2]

The diversity of molecules found in oils and in polymers has stimulated the development of innovative chromatographic and mass spectrometric approaches to generate “fingerprints” at the molecular level. In this talk, we will present some of our latest developments in this field: Concerning heteroatom and metals containing molecules in crude oils, the complete distillation series of various crude oils have been studied using Gel Permeation Chromatography Inductively Coupled Plasma High Resolution Mass Spectrometry (GPC ICP HR MS).[3] Size distribution of sulfur, vanadium and nickel containing molecules or aggregates within an oil cut can then be determined, compared and studied through a refining process.

The coupling of atmospheric solid analysis probe (ASAP) with ion mobility-mass spectrometry (IM-MS) has been shown to be an efficient tool for the characterization of oil cuts,[4] polymers, polymer blends[1] and additives.[2] This approach affords the coupling of a direct ionization technique that does not require sample preparation, with a bi-dimensional separation method. It is therefore a useful tool for the rapid generation of molecular fingerprints from complex matrix samples.
