Model of an industrial multitubular reactor for methanol to formaldehyde oxidat...

In the present work, a first-principles model of methanol partial oxidation to formaldehyde in an industrial reactor was developed and the reaction kinetic and deactivation parameters estimated, taking advantage of the temperature profile established by the exothermic reaction. The catalyst deactivation was assigned primarily to hot-spot regions in the oxidation reactor. The exposure to high temperatures enhanc...

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 res...
