Enhanced fluidization of cohesive particles
Gas-solid fluidization is one of the most important techniques in the industry, as it excels at creating homogenous mixing and offering superior transport properties. Fine powders are broadly employed in the energy, chemical, and pharmaceutical sectors. For particle sizes below 20 μm, interparticle forces start to dominate, and particles tend to agglomerate. Therefore, achieving effective fluidization of fine particles becomes troublesome.
Introducing additional degrees of freedom provides flexibility to manipulate fluidization behavior. The aim of this project is to investigate industrially relevant assistance methods that prevail: vibration, pulsation, stirrer mixing, and high-velocity jets. By identifying the enhancement induced and uncovering the underlying mechanism, it will allow us to optimize existing reactors, and design a new class of efficient catalyst production.
