Model of an Industrial Reactor for Formaldehyde Production with Catalyst Deactivation

Abstract

This work focussed on the deactivation of molybdenum oxide installed in an industrial methanol oxidation reactor. The deactivation parameters were estimated using the operational data obtained during the entire lifetime of the previously installed catalyst and validated with the results from the new catalyst. The deactivation was calculated as a function of the total reagent consumption instead of time. The results presented a good agreement with the available industrial data and the resulting model will then be used for the description of the whole formaldehyde production process.
