Abstract
Chemical Reaction Engineering as a Bridge Between Nano and Macro World
Highlights
The main fields of chemistry belonging to Chemical Reaction Engineering (CRE) are thermodynamics, kinetics and catalysis (Levenspiel, 1998; Froment et al, 2010; Scott Fogler, 2016)
The classical kinetic approach provides the development of know-how about the conduction of a kinetic test, drawing the lines about the correct definition of the minimum number of experiments needed to understand the kinetics of a reaction network (Salmi et al, 2010; Santacesaria and Tesser, 2018)
For example, when simulating continuous reactors, the momentum balance equations are neglected, and the fluiddynamics is described in terms of pressure-drop correlations. This approach is usually valid, but what if the geometry of the packing is non-conventional? What if the fluid-dynamics is far from being classical? It has been demonstrated that CFD modeling can be coupled with a classical kinetic approach to consider irregular geometries of non-conventional packing materials, such as foams (Della Torre et al, 2016)
Summary
Chemical Reaction Engineering started its history with the development of refinery and petrochemical industry at the beginning of the last century (Levenspiel, 1980). That optimization of process performance demands for the merge of fundamentals sciences (chemistry, physics, mathematics—reactor modeling) in a new applied discipline: Chemical Reaction Engineering (CRE) (Levenspiel, 1998; Froment et al, 2010; Scott Fogler, 2016).
