Abstract:
The invention relates to a method for catalytically producing formic acid and regenerating the catalyst used in the process. A vanadyl ion, vandate ion, or polyoxometallate ion, which is used as the catalyst, of the general formula [PMo x V y O 40 ] n−  is brought into contact with an alpha hydroxyl aldehyde, an alpha hydroxy carboxylic acid, a carbohydrate, a glycoside, or a polymer, which contains a carbon chain and which comprises at least one OH group that is bound to the carbon chain as a substituent in a repeating manner and/or an O, N, or S atom contained in the carbon chain in a repeating manner, in a liquid solution ( 12 ) in a vessel ( 10 ) at a temperature above 70° C. and below 160° C., wherein 6≤x≤11, 1≤y≤6, 3<n<10, and x+y=12, where n, x, and y is each a whole number. The catalyst reduced in the process is returned to its starting state by oxidation. For this purpose, the solution ( 12 ) is brought into contact with a gas ( 18 ) which contains a volume percent of oxygen of at least 18% at a pressure of at least 2 bar and maximally 16 bar by means of a mixing device or via a liquid-non-permeable gas-permeable membrane. CO and/or CO 2  resulting during the reaction and merging with the gas ( 18 ) is discharged in such a quantity that the volume percent of CO and CO 2  combined does not exceed 80% in the gas ( 18 ).

Claim (Index 10):
The method as claimed in  claim 1 , where the mixing apparatus is designed in such a way and operated in such a way, or the membrane is constructed in such a way, that the surface area of the solution is increased by a factor of at least 1000 as a result.
