Formox process
The Formox process produces
Perstorp and Reichhold Chemicals .[2]
Industrially, formaldehyde is produced by
oxidation of methanol. The most commonly used catalysts are silver metal or a mixture of an iron oxide with molybdenum and/or vanadium. In the recently more commonly used Formox process using iron oxide and molybdenum and/or vanadium, methanol and oxygen
react at 300-400°C to produce formaldehyde according to the chemical equation:
- H2O.
The silver-based catalyst is usually operated at a higher temperature, about 650 °C. On it, two chemical reactions simultaneously produce formaldehyde: the one shown above, and the dehydrogenation reaction:
Further oxidation of the formaldehyde product during its production usually gives
parts per million
values.
