Method for the production of formaldehyde
View Patent ↗A method for formaldehyde production through catalytic oxidation of methanol, comprising the steps of feeding to a first oxidation catalytic bed ( 2 ) a gas flow comprising methanol and oxygen at a predetermined crossing linear flow rate, obtaining at the outlet of said first catalytic bed ( 2 ) a flow of gaseous reaction products comprising unreacted methanol, and feeding the flow of gaseous products to a second oxidation catalytic bed ( 6 ) is distinguished by the fact that the flow of gaseous reaction products comprising unreacted methanol is fed to the second catalytic bed ( 6 ) with a crossing linear flow rate substantially equal to said predetermined first catalytic bed ( 2 ) feeding flow rate.
1. A method for the production of formaldehyde 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 velocity, obtaining at the outlet of said first catalytic bed a flow of gaseous reaction products comprising unreacted methanol; and
feeding said flow of gaseous products to a second oxidation catalytic bed;
wherein said flow of gaseous reaction products comprising unreacted methanol is fed to said second catalytic bed with a crossing linear flow velocity substantially equal to said predetermined first catalytic bed feeding flow velocity.
2. The method according to claim 1 , wherein said gaseous reaction products fed to said second catalytic bed have a temperature that is controlled in a temperature range comprised between 200 and 300 C.
3. The method according to claim 2 , wherein said temperature range is comprised between 210 and 260 C.
