The study of fluidization fast pyrolysis of straw based on the biomass entrained flow gasification
The straw is considered to be a kind of low heating value biomass. A new entrained flow gasification process to utilize the straw was proposed and introduced fast pyrolysis as a straw pretreatment unit for this process. This study was focus on the key factors influencing on the pyrolysis products of straw and optimized the pyrolysis condition based on the analysis results to meets the needs for biomass-slurry entrained flow gasification. Experiments were carried out at the temperature ranged from 400 to 600 ℃, heating rate around 500-1000 ℃/s. Under the certain particle size and optimized fluidization flow, the maximum liquid product yield was 43.1% at the temperature of 400 ℃ and the maximum solid product yield was 41..9% at the temperature of 400 ℃. The characteristics of both liquid and solid products relevant to the gasification applications were analyzed. The results showed that the energy density of the products were far more higher than the crude straws. Finally, an optimal pyrolysis condition was proposed, which was considered to be a suitable feedstock solution for the biomass-slurry entrained flow gasification.
