A procedure to transform a precursor of a catalyst based on a mixed oxide of Vanadium and Phosphorus in the active Catalyst for the production of maleic anhydride,Active Catalyst obtained by this procedure and Procedure for preparing maleic anhydride using Said Catalyst Active

摘要

Refers to the transformation of a precursor of a catalyst based on a mixed oxide of Vanadium and Phosphorus in the active Catalyst for production of maleic anhydride.Activation takes place in a fluidized bed and include: (a) s stages of initial heating of the precursor; (b) subsequent heating pressure superatomosfu00e9rica Isothermal pressure Stage; (c)The superatmosfu00e9rica and finally (d) catalizadoractivado Cooling has been obtained.Loscatalizadores that have been activated under this procedure Exhibit High yields in non Aromatic conversion hours in maleic anhydride.It also relates to a method for prepararanhidrido improved maleic.
