Verfahren zur Herstellung von Formaldehyd |
摘要 |
Process for the preparation of formaldehyde through oxidative dehydrogenation of methanol characterized in that a gas mixture containing: a) 0.1 to 50 vol. % methanol, b) 0.1 to 30 vol. % oxygen, c) 0.1 to 50 vol. % nitrogen oxide and d) 0 to 60 vol. % water; is led to a phosphor-doped silver catalyst fixed bed (a) at a temperature of 150 to 800 DEG C and where is deposited on the phosphor-doped silver catalyst fixed bed (a) 0.01 to 100 wt.ppm phosphor, in relation to the phosphor-doped silver catalyst fixed bed, in the form of a finely distributed phosphor compound with a melting or decomposition temperature of more than 500 DEG C (phosphor compound P) per kg methanol led through the phosphor-doped silver catalyst fixed bed (a) in the form of the gas mixture (i), per cm<2> of the cross-sectional area of the bed (a).
