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 t
