AbstractApplication of Magnetic Microparticles in Chemical Engineering Technology In chemical engineering technology microparticles are used in a diversity of fields. Particles with essential chemical characteristics and additional magnetic properties open new opportunities for developing novel processes in many areas. Separation processes such as adsorption and chromatography as well as reactions with catalysts are especially interesting applications. A high specific surface is advantageous for most of these unit operations. Because of the small size of the particles used their handling is not trivial. The magnetically stabilized fluidized bed (MSFB) is a promising example of a magnetically assisted process. This technology permits design of new processes whose favorable operations conditions lie outside the range of conventional operation. Common to all applications is that the magnetic properties of the particles provide a new free and adjustable parameter for managing the process.
