How does reactor geometry impact chemical reaction performance?

Void Fraction and/or Porosity is also a key element i.e., in multiphase reacttions the ratio between the gas phase area and the total flow area is very important for the reaction kinetics and selectivity.

Reactor geometry significantly influences chemical reaction performance. The ratio of surface area to volume impacts heat and mass transfer, while the shape dictates mixing efficiency and residence time. Efficient heat transfer and pressure drop, influenced by geometry, are critical for controlling temperature and reaction feasibility. Flow patterns, scalability challenges, and catalyst distribution are also affected. Reactor design directly influences safety considerations and can impact the selectivity of reactions. A thoughtful approach to reactor geometry is crucial for optimizing efficiency, ensuring safety, and achieving successful chemical processes.

If the rate of the reaction is positive on the reactants, then one could achieve a given conversion in a plug flow reactor (PFR) that is smaller in size than a continuously stirred tank reactor (CSTR). The opposite is true for chemistries with negative reaction orders on the reactants. To deal with reaction that are highly exothermic or endothermic, one could think of multitubular reactors. E.g. steam reforming or ethylene oxide production. If the catalyst deactivates quickly, let's say in matter of seconds, fluidize bed systems come into play. A typical example is FCC. My favourite geometry are the spherical reactors. They give little pressure drop which may be critical in chemistries where the number of moles increases

I would think about the quality of mixing, the better mixing the more uniform the temperature and pressure profiles, Also pressure drop through the reactor.

Are you sure you mean "spherical" or do you mean "radial flow reactors". The latter are used for things like ethylbenzene to styrene conversions and have the super low pressure drops you mention. Only spherical reactors I've ever seen are ones I've previously used for gas-phase polyolefins synthesis. But never for fixed-bed or classical heterogeneous catalyst applications.

A >>> B+C Understanding the thermodynamic basics of Gibbs Free Energy for the product & reactants are instrumental to determine the reaction equilibrium conversion. It is worth mentioning that the determination of the equilibrium conversion will conclude the operating temperature and pressure for the reaction. The latter two variables are key parameters for reactor sizing
