  • Methanol oxidation over bulk metal vanadate catalysts
    Patent number: 7193117
    Abstract: A method wherein a methanol-containing gas stream is passed in contact with a catalyst comprising a supported or unsupported bulk vanadate catalyst in the presence of an oxidizing agent for a time sufficient to convert at least a portion of the methanol to formaldehyde (CH2O).
    Type: Grant
    Filed: December 20, 2002
    Date of Patent: March 20, 2007
    Assignee: Lehigh University
    Inventors: Israel E Wachs, Laura E Briand
  • In situ formation of metal-molybdate catalysts for methanol oxidation to formaldehyde
    Patent number: 6624332
    Abstract: The method of the present invention involves the in situ formation of metal-molybdate catalyst particles active for methanol oxidation to formaldehyde, with iron as an example, the catalyst is made by mixing particulate forms of Fe2O3 and MoO3 which form an active Fe2(MoO4)3/MoO3 component inside the reactor during methanol oxidation.
    Type: Grant

  • In situ regeneration of metal-molybdate catalysts for methanol oxidation to formaldehyde
    Patent number: 6037290
    Abstract: The method of the present invention involves in situ regeneration of metal-molybdate catalyst for methanol oxidation to formaldehyde comprising the step of regenerating spent metal-molybdate catalyst with an oxygen-free gas stream comprising methanol and an inert gas for a sufficient time and at an elevated temperature to regenerate the metal-molybdate catalyst.
