Abstract
ABSTRACT The presence of n-alkanes in jet fuel can be explained if large n-alkanes are present in the crude oil source. Quantities of large n-alkanes present in crudes made from shale are insufficient, however, to explain the amounts found (up to 37%) in jet fuel made from these crudes. Although possible precursors to small n-alkanes are branched alkanes or substituted cyclic compounds, this paper shows that attack in the side chain of model pyridine compounds, similar to those found in shale crudes, affords a path to significant yields of n-alkanes. This study shows free radical attack at the alpha and gamma positions in the side chain to be favored. The major initial product distribution can be explained on the basis of Fabuss-Smith-Satterfield theory.
