The operating range suitable for three-phase reaction was obtained and a mathematical model established. The results show that MSB formed by fine magnetizable powder and fliudizing flow can be operated stably in a wide range. MSB has three kinds of regimes: particulate, chain, and magnetically condensed. In these regimes, the chain regime is the best for three-phase reaction.
