| 摘要 |
A hydrotreating process wherein composite catalyst particles are formed into a magnetically stabilized fluidized bed and contacted with a fluid, preferably gas. The composition is one which exhibits high induced magnetism in a small applied magnetic field when formed into a magnetically stabilized fluidized bed. The particles contain a non-ferromagnetic component, or components, composited with one or a plurality of elongated ferromagnetic components, oriented and present in each of said particles in relatively low concentration, based on the total volume of the particles.
