The characteristics of a magnetically stabilized bed (MSB) were studied by cold‐model experiments, using water as liquid phase, hydrogen as gas phase, and γ‐Fe 2 O 3 magnetic powder as solid phase. The fluidized state of different bed positions was investigated by testing the transmissible laser current. Effects of magnetic field intensity and gas flow rate on layer expansion states of the MSB were analyzed by color diagrams. A Ru‐Zn‐B amorphous alloy was prepared by chemical reduction. Selective hydrogenation of benzene was carried out in the MSB by adjusting the contact time between the catalysts and reactants through variations of reaction temperature, magnetic field current, and liquid hourly space velocity.
