Experimental and Kinetic Studies of Ethylene Glycol Autoignition at High Temperatures.

ABSTRACT: As one of the simplest polyols with chemical properties of alcohol, ethylene glycol is considered as a renewable energy source and a model fuel for pyrolysis oil. In this work, autoignition characteristics of ethylene glycol have been investigated behind reflected shock waves. Experiments were conducted at pressures of 2, 5, and 10 atm, equivalence ratios of 0.5, 1.0, and 2.0, and temperatures ranging from approximately 1200 to 1600 K. The fuel concentration was also varied. Results show that the ignition delay time increases with decreasing the pressure or fuel concentration. A strong positive dependence upon the equivalence ratio was found. A quantitative relationship has been yielded by the regression analysis of the experimental data. Simulations were carried out using chemical kinetic
