Fluidised bed olefin ammoxidation - using iron tellurium molybdenum catalyst in microsphere form

摘要

The catalyst system for ammoxidation of olefines to nitriles consists of Mo, Te, Fe oxides and/or iron n and/or tellurium telluromolybdate supported on silica in the form of microspheres diameter pref. 50-200 mu. Catalyst shows high attrition resistance.
