In the previous study, a dynamic and two-dimensional model for a steam methane reforming process integrated with nuclear heat production was developed. It was shown that the integrated high temperature gas-cooled reactor (HTGR)/steam methane reforming (SMR) is an efficient process for applications such as hydrogen production. In this study, it is demonstrated that combining nuclear heat with the mix of steam and dry reforming process can be a promising option to achieve certain desired H₂/CO ratios for Fischer–Tropsch or other downstream energy conversion processes. The model developed in the previous study is extended to the combined steam and dry reforming process. The resulting model was validated using reported experimental data at nonequilibrium and equilibrium conditions. The dynamic and steady state performance of the integrated mixed reforming of methane and nuclear heat system was studied, and it was found that in addition to desired H₂/CO ratios, higher methane conversion and lower CO₂ emissions can be achieved using the proposed design compared to the HTGR/SMR system.

混合重整和无碳热源系统的动力学建模

在先前的研究中，建立了与核热生产相结合的蒸汽甲烷重整过程的动态二维模型。结果表明，集成的高温气冷反应器（HTGR）/蒸汽甲烷重整（SMR）是用于制氢等应用的有效方法。在这项研究中，证明了将核能与蒸汽和干重整过程相结合可以成为实现某些所需H ₂的有前途的选择。费-托或其他下游能源转换过程的/ CO比。先前研究中开发的模型扩展到蒸汽和干重整工艺的组合。使用非平衡和平衡条件下报告的实验数据验证了所得模型。研究了甲烷与核热系统的混合混合重整的动态和稳态性能，发现除了所希望的H ₂ / CO比之外，使用所提出的设计还可以实现更高的甲烷转化率和更低的CO ₂排放量与HTGR / SMR系统相比。
