“…This decrease in heat sink was attributed to the sharp decrease in temperature after the initial cracking reaction and the formation of filamentous coke. Filamentous coke present on the surface of stainless steel can react with nickel or iron, inducing surface deactivation. , The M1-coated reactor showed endothermic reactions similar to those of thermal cracking, showing 1037, 839, and 876 Btu/lb values. It was concluded that the lower coating weight of alumina in this case had little effect on the durability of the tube protection.…”

To manage heat generated during the supersonic flight of aircraft, hydrocarbon cracking reactions were proposed. To suppress cracking reactions occurring within stainless steel walls of fuel flow, an alumina coating was applied. By optimizing the pretreatment of stainless steel and the number of alumina coating cycles, an optimal method for alumina coating was identified. Alumina coating under optimal conditions exhibited minimal weight loss, even under ultrasonic vibration. Furthermore, it was found that the coated alumina exhibited a heat absorption reaction, resulting in 887 Btu/lb with suppression of surface catalytic reactions and a predominance of pure thermal cracking reactions. The change in heat absorption over time could be suppressed from 16 to 2.3%, and the coke formed on the wall was decreased by over 35% from 98 to 63.3 mg. Moreover, it was observed that incorporating the HZSM5 catalyst within the alumina layer not only maintained wall durability but also enhanced heat absorption by over 15% compared to thermal cracking.
