Steam methane reforming (SMR) is a widely adopted method for H₂ production due to its advantages in the maturity of technology and economic feasibility. Since the optimization of an SMR reactor in the overall H₂ production process is important to reduce energy loss and increase productivity, the analysis of the reactor is essential. However, in order to increase the efficiency of the entire H₂ production process, it is necessary to analyze the entire process in an integrated manner rather than focusing on an SMR reactor. To this end, we develop a computational fluid dynamics (CFD) model of the SMR reactor and integrate it with the H₂ production process based on experimental data, to simultaneously evaluate the H₂ productivity and process thermal efficiency. The reactor yield and process efficiency according to operating conditions were evaluated by combining the exact rate of heat transfer of the SMR reactor into process simulation. The integration model achieved higher accuracy of modeling the process than the individual modeling of the SMR reactor and the H₂ production process. From the parametric study via the integration model, the most advantageous set of operating conditions of the H₂ production process is proposed.

蒸汽甲烷重整（SMR）由于其技术成熟度和经济可行性等优势，是一种被广泛采用的H ₂生产方法。由于在整个 H ₂生产过程中优化 SMR 反应器对于减少能量损失和提高生产率很重要，因此对反应器的分析至关重要。然而，为了提高整个H ₂生产过程的效率，有必要以整体的方式分析整个过程，而不是专注于SMR反应器。为此，我们开发了 SMR 反应器的计算流体动力学 (CFD) 模型，并将其与基于实验数据的 H ₂生产过程相结合，以同时评估 H ₂生产率和工艺热效率。通过将 SMR 反应器的准确传热速率与工艺模拟相结合，评估了根据操作条件的反应器产率和工艺效率。与SMR反应器和H ₂生产过程的单独建模相比，集成模型实现了更高的过程建模精度。通过集成模型的参数研究，提出了H ₂生产过程中最有利的一组操作条件。
