Abstract

The focus of this study is on combustion modeling of synthetic Gas-To-Liquid (GTL) kerosene produced via the Fischer-Tropsch synthesis route from Natural Gas. The input formula of surrogate (IFS) is determined from the optimization of a set of criteria (enthalpy of formation, density, C/H ratio, viscosity, sooting tendency index, two phase diagram, distillation curve, and ignition delay), which has been extended by the cetane number (CN) in this work. CN depends on both the chemical and the physical characteristics of the fuel, the molecular structure of its constituent hydrocarbons, and can be used to count the ratio of mono-branched to multi-branched iso-paraffins in the fuel. The proposed surrogate consists of 17% of 2,7-dimethyloctane, 32% of 2-methyldecane, 15% of n-propylcyclohexane and 36% of n-decane. Due to the lack of data for 2,7-dimethyloctane and 2-methyldecane two simplified surrogates composed of n-decane, n-propylcyclohexane, and iso-octane 2-methyldecane have been suggested. For that the chemical kinetic model for a mono iso-paraffin, 2-methyldecane, has been developed. The experimental data for ignition delay of GTL kerosene have been modeled using these two simplified surrogates and results have been compared.
