The detailed composition description of poly (ethylene terephthalate)(PET) pyrolysis
products still remains a challenge due to the complexity of the obtained mixture. In this …

Naphthenic acids are recognized as the main corrosive species in acidic crude oils,
although they represent less than 3 wt%. Alternative methods have been developed in an …

Thousands of chemically distinct compounds are encountered in fossil oil samples that
require rapid screening and accurate identification. In the present paper, we show for the …

Two methods of asphaltenes fractionation have been employed to facilitate the
characterization of their respective subfractions. The methods are based on step-wise …

Naphthenic acids were identified as the main corrosive species in acidic crudes, although
they represent less than 3% wt. The determination of naphthenic acid concentration in oils is …

As one of the major fractions of petroleum and/or source rock extracts, asphaltene is
commonly characte-rized by complicate molecular structures as well as relatively higher …

Characterization of challenging and/or new energy materials (eg, biomass/biofuels, heavy
oils, and solid petroleum products) requires the generation of new and improved analytical …

Heavy oil fractions studies are of great importance for the oil industry, receiving particular
attention in recent decades due to interest in obtaining compounds with higher added value …

The presence of fullerenes as natural constituents of carbonaceous materials or their
formation as laser artifacts during laser desorption ionization (LDI) mass spectrometry (MS) …

Due to the intrinsic complexity of crude oil, the advanced chemical compositional analysis
would be required to detect the crucial interactions that may take place between water and …
