Abstract
We develop a dynamic model with temperature as the control variable and simplified reaction networks to investigate the potential benefits of periodic pulse heating for endothermic gas-phase reactions. The results suggest that dynamic electrification of gas-phase reactions could substantially improve the conversion compared to steady-state heating for a first-order reversible endothermic reaction and overcome equilibrium limitations under certain conditions. Series and parallel reactions demonstrate improvement in yield at a high pulsing frequency and amplitude in a certain temperature range. A data-driven approach is introduced to classify conditions for the enhanced performance of nonlinear systems under periodic operation. These revelations underscore the promising potential of implementing a temperature pulse heating strategy in practical applications, leveraging the existing body of knowledge to achieve superior outcomes. Finally, we explain recent experimental results and propose systems in which such behavior could be observed.
