Flow-promoting device, a reactor arrangement and the use of such flow-promoting device

A flow-promoting device for performing a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic medium, wherein:

• said flow-promoting device comprising a ferromagnetic material and a body formed by a fluid-permeable material, wherein the body comprises a top wall and a circumferential side wall, wherein the top wall and the circumferential side wall are formed mainly by said fluid-permeable material, and the fluid-permeable material contains at least one fluid-permeable solid reaction member,
• whereby when the flow-promoting device is submerged into a fluidic medium and the flow-promoting device is subjected to an alternating magnetic field, the flow-promoting device is set to rotate, thereby causing a flow of fluidic medium into and through said fluid-permeable material,
• wherein the fluid-permeable material includes one or more fluid-permeable self-supporting material(s) of spatially homogenous or composite design, which are provided by porous monoliths made from organic or inorganic precursors, open cell foams or sponges, porous (hydro)gels, cryogels, or a combination thereof, and
• wherein the ferromagnetic material is particulate, and is integrated and distributed in the body.

A reactor arrangement, the reactor arrangement comprising a rotatable flow-promoting device and a supporting structure,

• the rotatable flow promoting device comprising a ferromagnetic material and a retaining structure, the retaining structure having a compartment defined by a permeable mesh material, wherein
• the retaining structure comprises a top wall and a circumferential side wall, wherein the top wall and the circumferential side wall are formed mainly by said permeable mesh material, and
• the compartment of the retaining structure is arranged to contain at least one fluid-permeable solid reaction member,
• wherein the top wall has a continuous extension across its full surface extension and does not comprise any central inlet opening, whereby
• when the rotatable flow-promoting device is submerged into a fluidic medium and the rotatable flow-promoting device is subjected to an alternating magnetic field, the rotatable flow-promoting device is set to rotate, thereby causing a flow of fluidic medium into and through the compartment via said permeable mesh material;
• and
• wherein the supporting structure is arranged to removably receive the rotatable flow-promoting device, and allow the rotatable flow-promoting device to rotate inside the supporting structure when subjected to the alternating magnetic field.
