Heavy oil is an important resource in current petroleum exploitation, and the chemical composition information of heavy crucial for revealing its viscosity-inducing mechanism solving practical exploitation issues. In this study, techniques high-temperature gas chromatography high-resolution mass spectrometry equipped with electrospray ionization source were applied to reveal typical oils from western, central, eastern China. The results indicate that these display significant variations...
It is an important task for "petroleomics" to realize quantitative analysis of molecular composition crude oil. In this study, we proposed a strategy semiquantitative characterization whole The various compounds in oil was selectively analyzed by using electrospray ionization high-resolution mass spectrometry combined with chemical derivatization methods. Individual the were gas chromatography. results obtained from different methods further processed and integrated based on normalization...
Thiols (or mercaptans) are widely present in petroleum but generally trace amounts. Their formation and transformation important parts of the geochemical sulfur cycle, characterization these compounds is not comprehensive due to their thermal instability content. In this work, methylation/demethylation method was performed separate two condensate oils, while thiols therein were derived into alkyl methyl sulfides also isolated during process. There negligible thiophenes separated, separated...
Olefins are ubiquitous in processed petroleum streams undergoing thermal and catalytic cracking processes. However, the molecular characterization of olefins is often troublesome as a result presence cycloalkanes or aromatic hydrocarbons, which cannot be distinguished from each other because their identical composition. This study provides novel method to selectively characterize composition streams. The were converted into halohydrocarbons with iodine monochloride reaction reagent then...
Oil sludge deposition is a common phenomenon during oil transportation, storage, and processing. Detailed molecular characterization of sludges prerequisite for understanding the mechanisms emulsification, naphthenate, asphaltene deposition. In this study, naphthenic acids their salts in from an offshore platform were characterized by negative ion electrospray ionization Fourier transform cyclotron resonance mass spectrometry high-temperature chromatography (HTGC). The results show that...
γ-Al2O3 was incorporated with SiO2 and used as carrier to support Ni Cu oxides for catalytic ozonation of heavy oil produced water. The change activity in accordance that surface hydroxyl density after incorporation or reuse catalysts. Nitrogen adsorption X-ray power diffraction analysis indicated the specific area decreased mineral phase crystal structure metal unchanged incorporation. results confirmed neutral groups were active sites during ozonation. Increasing could be another way...
Heavy oil resources in the world are extremely abundant, and viscosity is currently main reference index for heavy classification. However, diversification of practical issues exploitation, refinement processing utilization urgently require support classification with more indexes. In this study, macroscopic properties typical oils China were analyzed, semi-quantitative analysis molecular composition different was completed based on high-resolution mass spectrometry. The results show that...
Polyglycolic acid (PGA) is a biologically friendly material with wide range of applications. The production dimethyl oxalate using coal-based syngas and the hydrogenation can produce polymerization raw PGA, glycolide, which requires methyl glycolate depolymerization process. intermediate products process were analyzed gas chromatogram-mass spectrometry (GC-MS) Orbitrap mass (Orbitrap MS), revealed presence cyclic linear PGAs different capped ends. impurities present in oligomer mostly...
Electrospray ionization (ESI) coupled with high-resolution mass spectrometry (HRMS) is rapidly developing into a powerful tool for the molecular characterization of petroleum fractions. However, occurrence ion–molecule aggregates seriously affects interpretation results. Ion–molecule are not inherent compounds in but they produced during analysis samples by spectrometry. Also, classes same as many petroleum. Therefore, removal these species crucial, and their from methods dissociation...
