Abstract

Oxidation of methanol on a chromium-molybdenum oxide catalyst proceeds via the scheme:

$$CH_3 OH\xrightarrow[{W_1 }]{{O_2 }}CH_2 O\xrightarrow[{W_2 }]{{O_2 }}CO$$

The following kinetic equations have been obtained

$$W_1 = \frac{{K_1 C_{CH_3 OH} }}{{1 + a_1 C_{CH_3 OH + a_2 } C_{H_2 O} }}$$

for the oxidation of methanol, and

$$W_2 = K_2 C_{CH_2 O} $$

for the oxidation of formaldehyde.

Abstract

Окисление метанола на хромомолибденовом окисном катализаторе идет по схеме:

$$CH_3 OH\xrightarrow[{W_1 }]{{O_2 }}CH_2 O\xrightarrow[{W_2 }]{{O_2 }}CO$$

Кинетические уравнения имеют вид: для окисления метанола

$$W_1 = \frac{{K_1 C_{CH_3 OH} }}{{1 + a_1 C_{CH_3 OH + a_2 } C_{H_2 O} }}$$

для окисления формальдегида

$$W_2 = K_2 C_{CH_2 O} $$
