Abstract
The invention relates to a method for producing formaldehyde from methanol by non-oxidative dehydrogenation, in a reactor, in the presence of a catalyst at a temperature between 300 and 1000° C. Said method is characterized in that the generation of the catalyst takes place spatially separate from the reactor and at a temperature greater than the dehydrogenation.
