This study develop a novel models for assessment of the conversion of biomass to valuable fuel products via fast pyrolysis. The simulation includes the pretreatment of the biomass, the pyrolysis reactor, and a combustion reactor. Simulating the each part of the process with the capacity of 2000t/d corn stover, the results show that energy consumption for the whole process is 468.73×109J/h and the generated energy is 531.6×109J/h,which means that energy generated was greater than the energy consumption; the energy consumption of product 1kg bio-oil is equivalent to 0.75883kg standard coal, while the energy generation was 0.8606kg standard coal.
