Abstract.

Biomass pyrolysis technology is the only way to obtain bio oil directly by thermo chemical method. Further research on the technology of straw pyrolysis is of great significance to promote the development of renewable energy industry. The research of pyrolysis kinetics model of is a part of basic research of biomass pyrolysis process. On the one hand, the study of pyrolysis kinetic model can reveal the physical and chemical changes in the process of pyrolysis, on the other hand, it can provide reference for optimization of pyrolysis process. The currently used in the main pyrolysis model is analyzed, and presents advantages and disadvantages, and put forward a new model of pyrolysis. Research hypotheses set biomass second step three competing reaction model parameters. Biomass first decomposition reaction, formation of water vapor and the activation state of biomass. Three parallel pyrolysis reactions of activated biomass, gas, coke and bio oil were generated, and the basic equation of model calculation was proposed.
