C10 Methyl Ester Surrogates for Biodiesel

Biodiesel surrogate mechanisms were developed using the detailed chemical kinetic mechanisms for n-heptane and for the methyl esters, methyl-decanoate, and methyl 9 decenoate. These models were compared with experiments in a jet stirred reactor of rapeseed oil methyl esters from 800-1400K at 10 atm and an equivalence ratio of 0.5. The surrogates were also compared to jet stirred reactor experiments of a mixture of methyl palmitate and n-decane. Methyl palmitate is a methyl ester that is actually contained in rapeseed and soybean derived biodiesel. The later experiments were conducted at 550–1100K, 1 atm and stoichiometric conditions.
