1. prepare a method for catalytic activity composition, described catalytic activity composition is the multielement oxide of containing element Mo and V and the hopcalite of at least one molybdenum, and described method comprises following methods step:

  • -use the elemental constituent source of multielement oxide to obtain the aqueous solution, or waterborne suspension, condition is, in the process obtaining waterborne suspension, each source all experiences aqueous solution state.-spray drying aqueous solution or waterborne suspension, to obtain spraying powder P,-use spraying powder P and add the oxide S of the molybdenum of at least one powdery and optionally add one or more shaping additives, and after component described in Homogeneous phase mixing, form the precursor (geometrical figuration body) of geometrical figuration with gained mixture, and-heat treatment geometrical figuration precursor, to form catalytic activity composition.
