Pyrolysis of Low and High Density Polyethylene. Part II: Analysis of Liquid Products Using FTIR and NMR Spectroscopy

Abstract

The pyrolysis of low- and high-density polyethylene (LDPE, HDPE) were investigated, and we characterized the liquid pyrolysis products. Pyrolysis experiments were carried out in a lab-scale batch-wise fixed-bed Pyrex® reactor, placed in a vertical furnace, and liquid products of the pyrolysis process were obtained. Nitrogen gas was used as carrier during the experiments, and the temperature was varied from 293 to 823 K. FTIR and ¹H, ¹³C NMR spectra were used to determine structural analysis of pyrolysis product.
