Pyrolysis of waste paper: Characterization and composition of pyrolysis oil

This article presents the results of an experimental study of waste paper pyrolysis in tubular furnace pyrolysis equipment. Pyrolysis of waste paper has been conducted in different pyrolysis temperatures and heating rates to investigate the product distribution and yields of pyrolysis products. The pyrolysis oil was characterized by elemental analysis and various chromatographic and spectroscopic techniques, which are HPLC, H-1 NMR, FTIR, and UV. The results of spectroscopic and chromatographic analysis show that there are four main different compounds in bio-oil: anhydrosugars, carboxyl compounds, carbonyl compounds and aromatic compounds.
