“…Microchannel reactors have even smaller volume/weight than monoliths, and easier scale-up. 68 Microstructured, monolithic and microchannel reactors are at a more advanced development phase than membrane reactors, displaying high conversion efficiency at moderate temperatures and offering great potential to develop the NH3 decomposition technology. 46 Although further investigations are needed into durability and robustness under dynamic conditions, such as frequent start-up and shutdown cycles, which are prevalent under realistic operations.…”
