Falling Bed Plasma Reactors

VALUE PROPOSITION

A large variety of applications require powdered materials to be treated by plasmas. Most applications used in the industry and research labs have a static configuration, where the powder samples are placed in a tray and stay still during the process. This is ineffective if the powders pile up in multiple layers since the plasma will interact more with the top layer compared to the bottom layer. In the Rotary Falling Bed Plasma Reactors all parts of the powders are treated and can be done on a large scale, uniformly and efficiently.

DESCRIPTION OF TECHNOLOGY

This technology is a Rotary Falling Bed Plasma Reactor system and method for efficiently processing powders. The system consists of a rotary reactor and a center plasma electrode, between which a plasma is generated. As the reactor rotates, the grooves in the reactor collect the powder at the bottom and release the powders from the top. As the powders fall through the plasma region, they effectively interact with the plasma species and are uniformly processed. As the powders fall from the top, they also move through the reactive plasma toward the gathering end where the plasma treated powders can be collected. Iintegrating sample feeding and sample collecting chambers to the rotary plasma reactor allows continuously treating powder materials.
