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.
