✦ Synopsis

Hydrocarbon product distributions have been determined from the decomposition of air-saturated, n-hexadecane vaporizing from a heated surface into a stream of heated nitrogen carrier gas. Surface temperature was varied over the range 482-313°C. Reaction products were measured primarily by gas chromatography. The fraction of fuel decomposed as hydrocarbon product, was found to increase with increased surface and carrier gas temperature, and was dependent upon the type of surface used. It was found that the ratio of oxygenated to hydrocarbon products decreases as temperature increases, particularly in the neighborhood of the transition point from nucleate to film boiling. It is concluded that liquid phase reactions play a more important role as temperature decreases, and oxidation reactions are more important in the liquid phase. Hydrocarbon product distributions are described over most of the range of experimental conditions by a radical chain mechanism.
