Abstract

The aim of this work was to study the effects of UF resin on the fast pyrolysis characteristics of waste wood packaging materials. Fast pyrolysis experiments were conducted on a fixed bed reactor and a py-GC/MS system specifically. The yield and products distribution in liquid product from UF resin, wood and particle board were compared as well as products distribution at different temperatures and with different resin amount. UF resin promoted the production of pyrolysis oil during fast pyrolysis of particle board. This effect increased with temperature, reached a peak value at 550 ℃, and decreased afterwards. The types and contents of nitrogenous products in liquid phase product obtained by fast pyrolysis of particle board was higher than those of wood. The contents of acids and phenols were also increased while the contents of ammonias, alcohols, aldehydes, esters and sugars were decreased to different extents. In conclusion, UF resin had little effect on the decomposition profile and types of products during fast pyrolysis of particle board, but showed a relatively large effect on the yield of pyrolysis oil and products distribution. The types, contents and distribution of nitrogenous products in liquid phase product were obviously affected by the pyrolysis temperature and content of UF resin in waste packaging wood materials.
