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.

Abstract: What is presented is an innovative design of a chemical reactor for catalytic breakdown of halogenated hydrocarbons, the body of which acts as a specialized electromagnet capable of immobilizing and retaining very large quantities of non-magnetized ferro-dia- or para-magnetic material-containing nano, micro-, or milli-particles within it's reactor volume despite high-velocity flow of any liquid through said reactor. This is accomplished without any pre-treatment to the nanoparticles, without the use of adhesive of any sort, electroplating, electrolytic action, nano-structured nanocages, membrane or other impregnation, or any other mechanical or chemical means.
