Fe-Sb-O Based Fluid-bed Catalysts Applied to Various Types of Ammoxidation Reactions

Yutaka Sasaki; Hiroshi Yamamoto; Kunio Mori; Kenichi Miyaki

Abstract Fe-Sb-O based fluid-bed catalysts promoted by appropriate additives are suitable for the ammoxidation of various organic compounds such as olefins, alcohols, alkyl-substituted (hetero)aromatic compounds, etc. The unique preparation method of the fluid-bed catalyst of this type is presented. It is characterized by the nitric acid oxidation of antimony trioxide catalyzed with iron ions. The catalysts thus prepared have superior catalytic and physical properties. Some examples of the commercial application of these catalysts are also presented. A new process for hydrogen cyanide production through methanol ammoxidation has recently emerged.
