The pyrolysis of phenolic resin was studied in a single-pulse shock tube at high temperatures between 1100 K and 1800 K. Considering the very high temperature and short duration time in a shock tube, the heat transfer process of sample particles in high temperature gas was analyzed and the heat equilibrium conditions between the phenolic resin powder and the ambient high temperature gas was also discussed. The pyrolysis product distribution and the pyrolysis rate constants of phenolic resin were determined using gas chromatograph and mass spectrometry. The major pyrolysis products were identified as water, carbon monoxide, hydrogen, acetylene and benzene. The pyrolysis process was divided into the lower and higher temperature regions at the temperature of 1400 K. The different dependency relationships of the pyrolysis rate constant with temperature for the lower and higher temperature regions were obtained. |
