The objective of this study is to systematically investigate the sooting behavior of terpenes and their hydrogenated analogues. Sooting tendencies were measured with a yield-based approach we developed recently , which offers several benefits compared to other approaches such as smoke point (SP): (1) it requires much smaller sample volumes, ~100 μL vs 10 mL ; (2) it has a much wider dynamic range; and (3) the flames can be computationally simulated to test kinetic mechanisms and develop insight into the soot formation chemistry . The first benefit was critical to this study since the hydrogenated terpenes had to be custom synthesized. However, since SP is used as the sooting tendency metric in the ASTM standards for petroleum-derived aviation fuels and synthetic aviation fuels , we derived a correlation between YSI and SP, and used it to estimate derived smoke points (DSP) for the terpenes. We also performed density functional theory (DFT) calculations to explain some of the differences observed in YSI.
