Characterization of Pyrolysis Liquids of Waste Wood-Based Board
We mainly characterized the compositions and basic properties of pyrolysis liquids of waste wood-based board in this study which can be a basic research for a further study of the possible application of the liquids. Compositions of pyrolysis liquids of wood-based board were analyzed by gas chromatography mass spectrometry (GC-MS). Basic properties of pyrolysis liquids including moisture content, density, diopter, pH and acidity were tested in the experiment. Results from GC-MS analysis show that pyrolysis liquids were influenced a lot by the nitrogen compounds transferred from urea formaldehyde (UF). Pyrolysis liquids are weak acetic to weak alkaline influenced by the pyrolysis compounds of UF adhesive. There are also some differences in properties between the pyrolysis liquids of medium density fiberboard (MDF) and particle board (PB). Future studies should be carried out to study the specific compositions and possible application of the liquids.
