A two-dimensional reactor model based on reaction kinetics and heat and mass transfer for catalytic NH₃ decomposition was constructed. A reactor design that minimizes the effect of endothermic reaction was investigated. It is difficult to design a single-tube reactor for NH₃ treatment at a flow rate of 10 m³/h because heat transfer from the reactor wall cannot keep up with the fast consumption of heat by the reaction, even under low space velocity conditions. The target conversion was achieved by decreasing the NH₃ supply rate. A reactor with a packed bed of suitable length was designed. Industrial-scale NH₃ treatment can be achieved using a multi-tube reactor.

建立了基于反应动力学和传热传质的NH ₃催化分解二维反应器模型。研究了使吸热反应的影响最小化的反应器设计。难以设计以10 m ³ / h的流速处理NH ₃的单管反应器，因为即使在低空速条件下，从反应器壁传热也无法跟上反应的快速热量消耗。 。通过降低NH ₃供给速率实现了目标转化率。设计了具有合适长度的填充床的反应器。使用多管反应器可以实现工业规模的NH ₃处理。
