Summary
Efficient feed injection into multiphase reactors for waste biomass conversion is crucial for assuring the process performance. In this work, a pressurized gas-solid feeder is utilized to inject a batch of sawdust powders into a fixed and fluidized bed cold-flow unit. The hydrodynamic features associated with biomass transportation by pressurized gas are characterized at different operating conditions through experimentation with a high-speed camera and CFD modelling. The operation map for this pulsed feeder was built by combining physical parameters that result in a certain transport flow regime in the injection line. The experimental results were compared with model predictions and the effect of different model parameters was investigated.
About the Speaker
Dr. Sina Tebianian obtained his PhD in fluidization at University of British Columbia under supervision of Prof. John Grace. Currently he works as research engineer at IFPEN on design and scale-up of several processes such as High-Severity FCC, biomass pyrolysis, chemical looping combustion and plastic recycling. He also performs fundamental research activities in the field of fluidization, supervising Master students, PhD candidates and Postdoc fellows.
