Volatile organic compounds (VOCs) are abundant in nature and can occur in various forms in a wide variety of sources. Petroleum is one of the major sources of VOCs. Petroleum being the most widely used energy resources of the world, often released to…
A better understanding of the nature of crude oil compounds that preferentially interact with certain types of solids is essential to visualize solutions to challenges in oil fields, such as enhancing the oil recovery factor, via wettability…
Characterization of challenging and/or new energy materials (e.g., biomass/biofuels, heavy oils, and solid petroleum products) requires the generation of new and improved analytical technologies. Matrix-assisted laser desorption/ionization (MALDI)…
High-resolution mass spectrometry enables molecular characterization of heavy petroleum fractions for petroleomics research. However, results from mass spectrometry are usually not quantitative. This paper provides strategies and solutions for…
Investigation on the use of diamondoids to assess the extent of thermal maturity, depositional environment, and origin of Niger Delta source rocks was carried out. This was done to evaluate the significant of diamondoids in petroleum exploration in…
A recently developed extrography separation method fractionates petroleum asphaltenes based on their ionization efficiency, which correlates with polarity, aggregation tendency, and asphaltene structure (single-core or island versus multicore or…
In this work, crude oil fractions obtained using n-pentane were analyzed using atmospheric pressure photoionization coupled to ultrahigh-resolution magnetic resonance mass spectrometry. The crude oil was supported on Ottawa sand and transferred to a…
Medium and heavy crude oils and high-boiling distillation fractions which are increasingly used in petroleum industry contain high concentrations of sulfur and metals. Their behavior in refining processes is critically dependent on the speciation.…
