Chemical characterization of petroleum is a challenging task due to its inherently complex
nature. For example, crude oil is believed to have as many or more compounds than the …

Owing to the increasing environmental and climate changes globally, there is an increasing
interest in the molecular‐level understanding of environmental organic compound mixtures …

For decades, discussion of asphaltene structure focused primarily on molecular weight. Now
that it is widely accepted that asphaltene monomers are between∼ 250 and 1200 g/mol …

The review discusses the achievements of the last 5 years in the field of using mass
spectrometry for the analysis of crude oils and some oil refining products. The presented …

Detailed structural information on sulfur-containing aromatic compounds in heavy oils is
valuable for the petroleum industry. In this work, Fourier transform ion cyclotron resonance …

Mass spectrometry is widely used in studying the structures of compounds present in crude
oil. In this study, a novel mass spectrometer incorporating a cyclic ion mobility separator was …

Forty years ago, Boduszynski published the first part in a series of manuscripts that
addressed the composition, and compositional progression of heavy oil. It concluded that …

The structural elucidation of hydrocarbons still remains a challenge for petroleomics
characterization using ultrahigh-resolution mass spectrometry (UHRMS). Double-bond …

Asphaltenes cause multiple problems in the petroleum industry, such as clogging crude oil
transportation pipelines and fouling catalysts. Characterization of the structures of the …

In coal chemistry, thermal dissolution (TD) is an effective processing technique to obtain
soluble components from coal by using organic solvents under a certain pressure and …
