Abstract
Screw reactors are suitable for biomass pyrolysis. Complex particle dynamics exist in screw reactors. In the present work, a 3D Eulerian multi-fluid model was developed in order to study the flow dynamics and back-mixing behavior of particles in a screw reactor. Distributions of particle volume fraction inside the screw reactor were obtained with the present model. The residence time distributions (RTD) of particles within the screw reactor were calculated with the virtual tracer method. The comparison between the predicted and the experimental results indicated that the present model was capable to accurately predict particle dynamics and RTD within a screw reactor. The particle RTD was then used to analyze the back-mixing behavior of particles inside the screw reactor. The present work can be used to analyze the performance of a screw reactor for use in biomass pyrolysis
