Analytical chemistry of liquid fuel sources: tar sands, oil shale, coal, and petroleum. Chapter 16. Olefin analysis in shale oils
The classical silica gel chromatographic method for determinination of percent olefins in shale oils was studied and found wanting, mainly because of cross-contamination from high levels of olefins and heteroatom-containing compounds. This paper describes a new hydroboration/oxidation procedure for olefins, and reports its use in hydrocarbon-type analysis of both whole shale oils and distillate fractions. Percent composition values for three whole oils ranged as follows: saturates, 13 to 26; olefins, 16 to 20; aromatics, 5 to 14; polar compounds, 41 to 62. A discussion of ir analysis for relative amounts of specific olefin types such as terminal, internal trans, and methylene structures is included.
