Abstract
A method for formaldehyde production through catalytic oxidation of methanol, comprising the steps of feeding to a first oxidation catalytic bed () a gas flow comprising methanol and oxygen at a predetermined crossing linear flow rate, obtaining at the outlet of said first catalytic bed () a flow of gaseous reaction products comprising unreacted methanol, and feeding the flow of gaseous products to a second oxidation catalytic bed () is distinguished by the fact that the flow of gaseous reaction products comprising unreacted methanol is fed to the second catalytic bed () with a crossing linear flow rate substantially equal to said predetermined first catalytic bed () feeding flow rate.
