Magnetofluidized G / L / S systems feature thc characteristics of increased particle terminal velocity which implies higher gas and liquid throughputs, bubble fragmentation which prolongs gas residence time and increases G / S interfacial area, effective retention of solid particles which arc otherwise easily buoyed upward due to adhering gas bubbles, and ready electric control of solids movement and transport. Basic understanding of thc behavior of ferromagnetic particles fluidized in a magnetic field is provided by both experimental observation and analysis of magnetofluidized L / S systems and of bubble breakup in magnetofluidized G / L / S systems. An example of the application of magnetofluidized G / L / S systems is given by an experimental ethanol bioreactor
