A method for preparing a catalyst of High Performance High resistance, especially suitable for the oxidation of methanol to formaldehyde

摘要

Method for preparing a catalyst for the oxidation of methanol to formaldehyde, which comprises a mix of catalytic System known as based Mixed oxides, Iron MOLYBDATE and Molybdenum TRIOXIDE with an amount of FERRIC oxide, such as vehicle, from 5 to 90% in PE So, with respect to the amount of mixed oxides fe2o3b ,The whole surface area of The Catalyst from 1 to 6 m2 / g, in which: (a) The Fe2O3 is chosen not Sintered Oxides and has a specific surface area of 3 m2 / g; (b) Fe2O3 and mechanically Mixed oxides are combined in a Weight ratio of 20:80 to in the presence of a 50: 50 L Ubricante and / or hydroxypropyl Cellulose as a Binder; (c) mo / fe molar ratio is between 2 and 3.
