Chemical analysis and property measurements of a catalytic hydrothermal conversion jet (CHCJ) fuel were used to formulate hydrocarbon mixtures for use as surrogates. Using conventional gas chromatography/(electron ionization) quadrupole mass spectrometry (GC/(EI)Q MS) advanced two-dimensional high resolution time-of-flight (GC×GC/(EI)TOF MS), CHCJ was found differ from Jet-A contain mostly linear alkanes, alkylcyclohexanes, alkylbenzenes, with small amounts branched alkanes multiring...
Linear alkanes are a class of compounds known to negatively affect the physical performance lubricant base oils. The ability rapidly identify and quantify linear in oils would enable oil companies more effectively evaluate their refinery methods for converting crude While mass spectrometry is powerful method elucidation structures complex mixtures, it not innately quantitative. An approach presented here identification quantitation samples by utilizing GC×GC/EI TOF MS. Identification was...
Although condensate oils are neither well defined nor have a known chemical composition, they considered by the petroleum industry to be good candidates for dilution of heavy crude oil as this generates blend with lower viscosity. This helps alleviate challenges in transportation, separation, and processing that mainly caused high concentration asphaltenes oils. However, these blends susceptible precipitation after dilution. Many factors can affect precipitation, including amount polar...
