*3.6. Acrolein Partial Oxidation Reaction Kinetics Validation*

Estenfelder and Lintz [7] presented reaction kinetics for the partial oxidation of acrolein over vanadium molybdate oxide catalysts with varying compositions. The reactor network was treated as an isothermal plug flow reactor and kinetics were presented for 533 K and 573 K. In order to approximate the kinetics for the temperature range from 533 K to 573 K, linearization of the experimentally determined reaction rate constants was used. Kinetic validations were conducted on Aspen Plus® (AspenTech, Bedford, MA, USA) to determine the feasibility of scaling up the lab-scale kinetics. The yield and selectivities reported by Estenfelder and Lintz [7] correlated with the Aspen Plus® (AspenTech, Bedford, MA, USA) simulation results in Table 2, thereby validating the use of these kinetics in the design of an industrial-sized reactor as well as reinforcing the ease of scale-up with multitubular reactors.
