Canadian central provinces are heavily dependent on fossil fuels production and existing pipelines do not support streaming pure hydrogen due to safety and technical issues. In 2019, Flaring and venting emitted about 6.5 Mton of CO2eq. A solution to this problem should be envisioned. The long term objective of this Discovery Grant (DG) is to develop a small-scale high residence time non-catalytic methane pyrolysis technology aimed at maximising hydrogen and carbon production, and to eliminate flaring, significantly reducing the green house gases emissions of the Canadian oil industry. Part of the hydrogen produced will maintain the extraction battery and generate the heat required for the process. The final reaction produces water, solid carbon, and energy. Currently, no solution is available for this high emitting industry as GtL technologies either co-produce CO2 or do not fully convert solution gas, which must be flared in any case. Also, recent technologies based on molten salts suffer from contamination problems and are characterized by heavy capital expenses (CAPEX). The objectives of this program are: 1. Understand the fundamentals of the non-catalytic pyrolysis reaction. Develop a kinetic model for natural gas pyrolysis, assess the influence of composition and process parameters on hydrogen yield and explore strategies to reduce carbon formation on reactor walls. Also, the boundaries of this research are not limited to natural gas, but also to other sources of energy that today are either burned or do not properly capture associated CO2 such as landfill gas and biogas. 2. Implementation of electrification, namely induction heating, to develop an intensified process which can eventually produce hydrogen for energy or other energy molecules such as methanol 3. Sets the framework for an environmental-technoeconomic process optimization. By coupling techno economic analysis and life cycle assessment (LCA) metrics, the design of an early stage process is truly optimized because it combines low cost and low environmental consequences. The main impacts of this DG research program will be 1. New technological approaches: This research will develop new reactor designs and envisage a new way to treat natural and biogas to produce hydrogen. 2.Economic: In Canada there are more than 3000 oil wells, and this number mounts when considering those in the USA. This new technology, never studied and optimized towards the abatement of flaring, has a huge economic return potential. Natural gas and landfill gas are targets of this technology. 3.Environmental: Gas and landfill flaring elimination will reduce about 1% of the total worldwide GHG emissions. 4. Training and formation of HQPs: The DG program and the technology I aim to study requires trained HQP to develop and operate these complex processes. Waste management, reactor design, and operation are among the future challenges and this DG will prepare and train versatile people to address them.

加拿大中央省份在很大程度上取决于化石燃料的生产，而现有的管道由于安全和技术问题而不支持流纯氢。 2019年，燃烧和通风发出约6.5米顿二氧化碳。应设想解决此问题的解决方案。该发现赠款（DG）的长期目标是开发一个小规模的高停留时间非催化甲烷热解技术，旨在最大化氢和碳的生产，并消除燃烧，从而大大减少加拿大石油行业的绿色房屋气体排放。所产生的氢的一部分将保持提取电池并产生该过程所需的热量。最终反应会产生水，固体碳和能量。当前，由于GTL技术要么共同生产CO2或不完全转换溶液气体，因此在任何情况下都必须爆发溶液的气体。同样，基于熔融盐的最新技术遭受污染问题，其特征是大量资本费用（CAPEX）。 该程序的目标是：1。了解非催化热解反应的基本原理。开发一种用于天然气热解的动力学模型，评估组成和过程参数对氢产量的影响，并探索减少反应堆壁上碳形成的策略。同样，这项研究的边界不仅限于天然气，还限于当今燃烧或无法正确捕获相关的二氧化碳（例如垃圾填埋气和沼气）的其他能源。 2。电气化的实施，即感应加热，以开发加强的过程，该过程最终可以为能量或其他能量分子（例如甲醇3）产生氢，为环境经济过程优化设定了框架。通过耦合技术经济分析和生命周期评估（LCA）指标，真正优化了早期过程的设计，因为它结合了低成本和低环境后果。该DG研究计划的主要影响将是1。新技术方法：该研究将开发新的反应堆设计，并设想一种新的方法来治疗自然和沼气以生产氢。 2.经济：在加拿大，有3000多口油井，在考虑美国的油井时，这个数字会安装。这项新技术从未研究和优化减少爆发，具有巨大的经济回报潜力。天然气和垃圾填埋气是该技术的目标。 3.环境：天然气和垃圾填埋场消除将减少全球气温剂排放量的1％。 4. HQP的培训和形成：DG计划和我旨在研究的技术需要训练有素的HQP来开发和运营这些复杂的过程。废物管理，反应堆设计和操作是未来的挑战，该DG将准备和培训多才多艺的人来解决这些问题。
