To enhance mass transfer efficiency,a flow-through catalytic membrane was fabricated and incorporated into a reactor system employing electromagnetic induction heating for ammonia decomposition to produce hydrogen.Computational methods were employed to determine the optimal structural parameters of the induction coil.Experimental results demonstrated a hydrogen production rate of 91.10 kmol/(m3·h) at 550℃,showing a 1.5-fold higher production rate than advanced microchannel reactors.Scale-up simulations indicated that at 500 Nm3/h production capacity,the system achieved 0.82 energy efficiency with a specific energy consumption of 0.73 kWh/Nm3-approximately one order of magnitude lower than water electrolysis.With ammonia feedstock costs factored in,the hydrogen production cost reached 23 CNY/kg,maintaining substantial competitiveness against electrolytic hydrogen.
