英文摘要： Straws and wood shavings will be used as raw material to prepare bio oil via pyrolysis liquefaction and the chemical mechanism of NTP-HZSM-5 synergetic catalytic pyrolysis will be revealed. GC-MS, TGA, FTIR methods will be adopted to analyze the chemical and physical properties of bio oil of varied raw material, and XPS and SEM will be applied to detect factors like material diversity which have impacts on catalyst performance. The emission spectrum of active particles of NTP will be monitored in real time. The regeneration of invalid HZSM-5 catalyst will be studied experimentally, on the basis of which a match model of NTP and catalyst will be established for elucidating the mechanism of regeneration process. NTP-HZSM-5 synergetic catalytic pyrolysis experiments will be performed with the combination of GC-MS, TGA, FTIR and OES, and then a chemical kinetic model will be built for exploring catalytic pyrolysis mechanism. Meanwhile, the components, themogravimetry, viscosity, caloricity，smoke point and other relative chemical and physical characteristics will be analyzed and evaluated, which will supply theoretical and experimental foundation for high efficiency catalytic pyrolysis of bio oil.
