Aerated Vibro-fluidization & Aerated Magnetically Assisted Fluidization of Nano-particles

Fluidization is a widely used process to achieve continuous powder handling ability, particle mixing and good solid-gas contacting. The process can also achieve high heat and mass transfer reaction rates. However, nano-particles are difficult to fluidize due to their strong inter-particle forces. Further, powder loss in conventional fluidized beds is hard to control.

Description of Invention
Coupling the flow of fluidized gas with a vibration force and/or a magnetic force dramatically changes the behavior of fluidization of nano-particles. By combining vibration and gas flow or by combining magnetic excitation and gas flow nano-particles were successfully fluidized.

Loss of powder during the processing is avoided and a controllable and smoother fluidization with good mixing characteristics and high bed expansion is achieved. The process is also usable for mixing or coating nano-particles without particle loss.

Business Opportunity
Partners are sought to assist in the commercialization of the technology.

Patent Status
A US patent application is pending.
