Detailed CFD modelling of fast pyrolysis of different biomass types in fluidized bed reactors

An Eulerian-Eulerian computational fluid dynamics model, combined with a comprehensive biomass reaction scheme, was applied to simulate fast pyrolysis of four different biomass types in the fluidized bed reactors. The influence of biomass components of different biomass types on the yields, formations, and contents of compositions of pyrolysis products were evaluated. The result showed that the bio-oil yield of cellulose-rich biomass was higher than other biomass types, and char was mainly produced by the fast pyrolysis of LIG-C of biomass. Also, the contents of bio-oil components were affected by the fast pyrolysis of biomass components. Additionally, the energy recovery coefficient of bio-oil obtained from pyrolysis of different biomass types was also calculated and analyzed.
