A new hydrogenation technology for caprolactam purification using amorphous Ni alloy catalyst and magnetically stabilized bed reactor has been developed by Sinopec. It shows significant advantages in industrial applications. Encouraged by this progress, a series of magnetic catalysts with both high catalytic activity and magnetic properties have been investigated, including amorphous metal alloy I metal oxides I bimetallic catalyst with magnetic metal oxide support and polymer magnetic catalytic materials. They have either metal active sites or proton active sites. Following reactions with these magnetic catalysts in magnetically stabilized reactor are evaluated: (1) hydrogenation of carbon monoxide for removing CO from hydrogen, (2) selective hydrogenation of alkynes in the olefins which are produced from hydrocarbon steam cracking for forming ethylene, (3) olefins oligomerization to produce diesel, (4) magnetic cation resin and isobutene etherification. Above researches are reviewed in this article. The future development on magnetic catalysts and magnetic stabilized bed reactor is also discussed.
