Endothermic decomposition reaction of methylcyclohexane (MCH) was conducted to solve problems of hypersonic flight as cooling technology. A wavy form microchannel reactor (WMCR) coated with H-ZSM-5 was used to improve this reaction. WMCR coated with H-ZSM-5 was simply prepared by using binder coating method. Field emission scanning electron microscope (FE-SEM) and energy dispersive spectroscopy (EDS) analysis were used to examine the surface of WMCR coated with H-ZSM-5. Endothermic decomposition reaction of MCH was carried out in a flow reactor under supercritical conditions (823 K and 50 bar) during 30 min. The liquid products produced by catalytic reaction were analyzed by gas chromatograph-mass selective detector (GC-MSD) at 10, 20 and 30 min, respectively. The results show that an increase in H-ZSM-5 coating amount on WMCR surface for catalytic reaction had a trade-off relationship; the increase of catalysts on WMCR had a positive effect on overall improvement of heat sink (from 416.59 kJ/mol to 611.06 kJ/mol) but simultaneously negative effect for catalytic life time because of increase in catalytic deactivation (from 5.9% to 30%).

进行甲基环己烷（MCH）的吸热分解反应以解决高超声速飞行作为冷却技术的问题。使用涂有 H-ZSM-5 的波浪形微通道反应器 (WMCR) 来改善该反应。用H-ZSM-5包覆的WMCR是用粘合剂包覆法简单制备的。使用场发射扫描电子显微镜 (FE-SEM) 和能量色散谱 (EDS) 分析来检查涂有 H-ZSM-5 的 WMCR 表面。MCH 的吸热分解反应在流动反应器中在超临界条件（823 K 和 50 bar）下进行 30 分钟。催化反应产生的液体产物分别在 10、20 和 30 分钟时通过气相色谱-质量选择检测器 (GC-MSD) 进行分析。结果表明，WMCR表面H-ZSM-5涂层量的增加对催化反应具有权衡关系；WMCR 上催化剂的增加对散热器的整体改善有积极影响（从 416.59 kJ/mol 到 611.06 kJ/mol），但同时由于催化失活增加（从 5.9% 到 30%）对催化寿命产生负面影响.
