Reactor design is a critical component of macro catalysis. The design and configuration of reactors significantly influence the efficiency and effectiveness of catalytic processes. Various types of reactors, such as fixed-bed reactors, fluidized-bed reactors, and continuous stirred-tank reactors (CSTR), are employed based on the nature of the catalytic reaction and the desired outcomes. Proper reactor design ensures optimal contact between reactants and the catalyst, uniform temperature distribution, and efficient removal of byproducts.
