摘　　要：以具有代表性的两类人造板废弃物——胶合板(PW)和纤维板(FB)为原料开展烘焙实验,结合元素、热值、傅里叶红外(FTIR)、二维相关红外(2D-PCIS)、X射线光电子能谱(XPS)等分析表征手段,探究烘焙预处理对人造板废弃物化学结构及其燃料品质的影响。结果表明,在200℃和250℃下,PW和FB烘焙固体产物化学结构变化并不明显,但在300℃下,发生明显变化。随着烘焙温度的升高,人造板废弃物中低能态的"—C—H/—C—O/—C==O"键向高能态的"芳香族—C—C/—C==C"键转变,燃料热值显著提高,并在300℃下,PW和FB获得最大脱氮效率,分别为75.04%和72.48%。The torrefaction experiments were carried out using two typical wood-based panel wastes:Plywood(PW)and Fiberboard(FB). The influences of torrefaction on chemical structure and fuel property of wood-based panel wastes were researched using the analytical characterization by combining with the element,calorific value,Fourier transform infrared spectroscopy(FTIR),twodimensional correlation infrared spectroscopy(2 D-PCIS)and X-ray photoelectron spectroscopy(XPS). The results show that the chemical structure of PW and FB do not change a lot at 200 ℃ even at 250 ℃,but at 300 ℃,significant changes will occur. With the increase of torrefaction temperature,the low-energy states of“ —C—H/—C—O/—C==O”change into the high-energy states of“aromatic —C—C/—C==C”,and the calorific value of torrefied solid increases significantly. Simultaneously,at 300 ℃,PW and FB obtain the maximum denitrogenation rate,which is 75.04 % and 72.48 %,respectively.
