Analytics Driving Kinetics: Advanced Mass Spectrometric Characterization of Petroleum Products

The current state-of-the-art analysis techniques for petroleum fractions has progressed substantially during the past decade. This helped to further improve lumping procedures and modeling approaches of these complex systems. Recent advances in gas chromatography (GC), GC-field ionization mass spectrometry (GC-FIMS), comprehensive (GC×GC) have made it possible determine compositions with up 45 carbon atoms some cases C80. combination MS other selective detectors reversed-phase column combinations quantify even traces heteroatomic compounds hydrocarbon matrices. Fourier-transform ion cyclotron resonance (FT-ICR-MS), combined GC×GC lighter part, pushed characterization larger macromolecules particular asphaltenes. Matrix-assisted laser desorption/ionization (MALDI) is also used widely this purpose but disadvantage that quantification not obvious. development more detailed remained unnoticed petrochemical society recently kinetic society. More implementation models simulation optimization including molecular detail. Additionally, photoionization (PI-MS) allowed detection reactive intermediates direct measurements time-resolved experiments. It can only be expected trend will continue application field move from now primarily petrochemistry (from catalytic cracking, over hydrotreating, hydrocracking pyrolysis, combustion, steam cracking) larger-scale chemical recycling biomass conversion processes.
