Abstract
A genre of media is presented for use with a reactor vessel and for the purpose of immobilizing small particles, often catalytic in nature. The media can include a number of ferromagnetic active wafers stacked together and separated by non-ferromagnetic separator portions, such that when in the presence of a magnetic field and magnetic-particle-containing fluid, at least some of the gaps between active wafers captures and suspends magnetic particles.
Claims23
An apparatus for immobilizing particles in a reactor vessel, comprising:
- a plurality of active wafers, each active wafer including ferromagnetic material and having a wafer magnetic permeability;
- and
- a plurality of separator pieces, each separator piece including non-ferromagnetic material, wherein:
- the plurality of active wafers and the plurality of separator pieces are coupled in a planar alternating manner to form a media stack, the media stack being physically permeable to a magnetic-particle-containing fluid having a fluid magnetic permeability that is low relative to the wafer magnetic permeability;
- and
- the media stack, when physically permeated by the fluid and magnetically permeated by a magnetic field, captures at least some of the magnetic particles between at least two of the plurality of active wafers creating a plurality of magnetic particle bridges between the at least two of the plurality of active wafers.
