Thermal Cracking of Phenolic-Nylon Pyrolysis Products on Passing Through a Heated Char.

Abstract

The pyrolysis products were generated by flash pyrolysis of the heat shield material in front of the heated char and were analyzed, after passing through the char, by gas chromatography. The change in composition of the pyrolysis products after passing through the char showed that the high molecular weight products cracked to lower molecular weight products, beginning at about 700 deg C. The low molecular weight products were found to increase with increasing char temperature and, at char temperatures approaching 1000 deg C, the pyrolysis gases were composed of carbon dioxide, carbon monoxide, water, methane, hydrogen, acetylene, benzene, and cyclopentanone.
