Özet
Formaldehyde is an important base chemical that is used in the production of urea-phenolic resins, paints,
cosmetics, explosives, textiles etc. Its demand is rising globally. Formaldehyde is produced industrially by the
catalytic oxidation of methanol. There are two typical industrial processes involving the conversion of methanol
to formaldehyde, that is, the dehydrogenation of methanol-rich air mixture over the silver catalyst and direct
oxidation of methanol-poor air mixture over the iron molybdate catalyst. The reaction obeys LHHW (Langmuir–
Hinshelwood) mechanism, which is suitable for computational simulations on iron molybdate catalysts. Thus, in
this work, it was aimed to simulate the partial oxidation of methanol in plug flow reactor over iron molybdate
catalyst using Aspen Plus simulation program. The reaction mechanism and kinetic data were obtained from the
literature. The effects of several important reaction parameters (reaction temperature, methanol flow rate, oxygen
flow rate, pressure and catalyst amount) were investigated and the optimum reaction conditions were determined.
