 Abstract: With the depletion of conventional resources, heavier and more sulfur-rich crude oils come into the focus of interest. However, the utilization of such feedstocks is extremely undesirable since their high sulfur content causes corrosion fouling, catalyst poisoning, and emissions of toxic pollutants into the atmosphere. As known catalyst poisoners, sulfur-containing compounds are also suspected to play an important role in crude oil fouling, that is, the formation of undesired solid deposits. To overcome these problems, insightful knowledge on the chemical composition of the sulfur-containing compounds on a molecular level and their behavior is necessary. Here, fouling reactions of a gas condensate were simulated in the laboratory under atmospheric and inert conditions, with special focus on sulfur-containing compounds, and the resulting mixtures were analyzed by using sophisticated analytical methods such as ultrahigh-resolution mass spectrometry and electron microscopy. The results indicate that sulfur-containing compounds decompose at elevated temperatures, partly by a radical-induced mechanism. Furthermore, the resulting intermediates show a limited stability in the presence of oxygen.
