Low Pressure Pyrolysis Experiment and Kinetic Modeling Study of 2, 5-Dimethyltetrahydrofuran

2, 5-dimethyltetrahydrofuran is considered as a very promising biomass fuel. In this study, the pyrolysis of 2, 5-dimethyltetrahydrofuran was studied in a flow reactor using synchrotron vacuum ultraviolet photoionization mass spectrometry (SVUV-PIMS) at the pressure of 3990 Pa and the temperatures from 948 to 1198 K. More than 40 pyrolysis species were identified and their mole fraction profiles were measured as function of temperature, including stable products and several free radicals. Based on the experimental results, a detailed kinetic model consisting of 265 species and 1490 reactions was proposed and verified by using the experimental results. Besides, by rate of production (ROP) analysis, the primary dissociation process of the fuel and formation pathways of the main products were obtained.
