Effects of urea formaldehyde resin and melamine urea formaldehyde resin on eucalyptus pyrolysis liquid

In order to effectively process wood-based panel waste by pyrolysis technology process, the effects of adhesives on wood pyrolysis liquid products was studied in this paper. GC/ MS technique was used to analyze the pyrolysis liquids of eucalyptus, eucalyptus with 10% UF resin, eucalyptus with 10% MUF resin, UF resin and MUF resin. The results showed that the composition of eucalyptus pyrolysis liquid was complex, in which the relative content of 2,5-dimethylfuran reached 27.54%, and that of 2-hydroxy- 3-methyl-2-cyclopenten-1-one and 4-( 2-oxopropyl )-2-cyclohexen-1-one were 7.03% and 7.01% respectively, and 2,6-dimethoxy-phenol was 9.47%. The relative amount of nitrogenous substance in the pyrolysis liquids of eucalyptus with UF resin was 22.92% more than that in the pyrolysis liquid of eucalyptus wood. The pyrolysis liquid could be utilized in the production of fertilizer and soil amendment. The composition in the pyrolysis liquid of eucalyptus with MUF resin contained xylose and butyrrolactone which could not be detected in the pyrolysis liquid of eucalyptus. This study could provide theoretical foundation for utilization of the abandoned wood-based panel rationally.
