Natural gas into hydrogen and graphite has the potential to be highly disruptive and presents substantial value if the process can be scaled up to commercial quantities. Hydrogen is the energy source considered an increasingly vital component of low carbon future. Potential to capture all the value in natural gas and benefit from exposure to several high growth markets (including the graphite market for Li ion batteries and the hydrogen market for fuel cell technology). The established industrial hydrogen and graphite markets are currently worth over $100bn and $13bn, respectively.The methane cracking process is well understood however, there is a need to design a reactor that optimises the reaction. The main requirement of the reactor is to reduce/nullify CO2 emission from the process. There should be the incorporation of the process in which the carbon is captured "clean" as graphite rather than vented "dirty" as CO2, as is the case for most current hydrogen production methods. Other challenges include safe removal of carbon produced, continuous methane cracking, replacement of catalyst, pressure building, clogging of catalyst, and continuous removal of carbides. Therefore, there is a big gap that this research can fill in by designing the optimised reactor for the proposed reaction by means of different simulation tools like CFD (Star CCM & COMSOL).

将天然气转化为氢气和石墨有可能具有高度破坏性，如果该过程可以扩大到商业数量，则具有巨大的价值。氢被认为是低碳未来日益重要的组成部分。有潜力获取天然气的所有价值，并受益于几个高增长市场（包括锂离子电池的石墨市场和燃料电池技术的氢市场）。已建立的工业氢和石墨市场目前价值分别超过 1000 亿美元和 130 亿美元。甲烷裂化过程众所周知，但需要设计一个优化反应的反应器。反应器的主要要求是减少/消除过程中的二氧化碳排放。应该纳入这样的过程，其中碳被“干净”地捕获为石墨，而不是像大多数当前氢气生产方法那样“肮脏”地排放为二氧化碳。其他挑战包括安全去除产生的碳、连续甲烷裂解、更换催化剂、压力增大、催化剂堵塞以及连续去除碳化物。因此，本研究可以通过使用 CFD（Star CCM 和 COMSOL）等不同的模拟工具为所提出的反应设计优化的反应器来填补很大的空白。
