A technical route for synthesizing the highgrade liquid fuel with the products of biomass pyrolysis was proposed. Experimental research on different paths in the route was conducted to obtain the clean motor fuel with high quality. Based on the optimized technological process in a fluidized bed reactor and the characteristic of Chinese biomass species, seven different biomass materials belonging to three species were selected as the samples, and a series of experiments were conducted for the production of biooil. The influences of biomass species to the yields and the properties of biooil were investigated. The diversities of biooil composition derived from different biomass species were presented based on the gas chromatographymass spectrometer (GCMS) analysis. Furthermore, the emulsification performance of different biooil with diesel was studied. The heating value of the emulsified fuel is close to that of diesel, and the viscosity accords with the national standard for light diesel oil, showing the potential for its commercial use. The distillates of biooil were separately upgraded by esterification, hydrogenation and gasification after pretreated by the molecular distillation.
