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).

天然气进入氢气和石墨具有高度破坏性的潜力，如果可以将过程扩展到商业量，则具有很大的价值。氢是低碳未来的越来越重要的能源。捕获天然气中所有价值并受益​​于几个高增长市场的潜力（包括李离子电池的石墨市场和燃料电池技术的氢市场）。既定的工业氢和石墨市场目前的价值分别超过1000亿美元和130亿美元。甲烷开裂过程已充分了解，但是，需要设计一种反应堆来优化反应。反应器的主要要求是减少/无效从过程中降低二氧化碳的发射。应像大多数当前的氢生产方法一样，将碳捕获为石墨而不是排气的“脏”的过程中，将碳捕获为石墨而不是排气“脏”。其他挑战包括安全去除产生的碳，连续的甲烷开裂，催化剂的替代，压力结构，催化剂的堵塞以及连续清除碳化物。因此，这项研究可以通过使用不同的仿真工具（例如CCM＆COMSOL）来设计优化反应器来填补这项研究的巨大差距。
