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.

加拿大中部省份严重依赖化石燃料生产，由于安全和技术问题，现有管道不支持输送纯氢。 2019 年，火炬燃烧和排放排放了约 6.5 百万吨二氧化碳当量。应该设想解决这个问题的方法。该发现补助金（DG）的长期目标是开发一种小规模高停留时间非催化甲烷热解技术，旨在最大限度地提高氢气和碳的产量，并消除火炬，从而显着减少加拿大的温室气体排放石油工业。产生的部分氢气将维持提取电池并产生该过程所需的热量。最终反应产生水、固体碳和能量。目前，对于这个高排放行业还没有可用的解决方案，因为 GtL 技术要么同时产生二氧化碳，要么不能完全转化溶解气体，无论如何都必须燃烧溶解气体。此外，基于熔盐的最新技术还存在污染问题，并且资本支出 (CAPEX) 较高。 该计划的目标是： 1. 了解非催化热解反应的基本原理。开发天然气热解动力学模型，评估成分和工艺参数对氢气产量的影响，并探索减少反应器壁碳形成的策略。此外，这项研究的范围不仅限于天然气，还包括当今要么燃烧要么无法正确捕获相关二氧化碳的其他能源，例如垃圾填埋气和沼气。 2. 实施电气化，即感应加热，以开发一种强化工艺，最终可以生产氢气作为能源或甲醇等其他能源分子 3. 为环境技术经济工艺优化设定框架。通过结合技术经济分析和生命周期评估（LCA）指标，早期工艺的设计得到了真正的优化，因为它结合了低成本和低环境影响。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器设计，并设想一种处理天然气和沼气生产氢气的新方法。 2.经济：加拿大有3000多口油井，考虑到美国的油井，这个数字还在增加。这项新技术从未针对减少火炬进行研究和优化，但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：消除天然气和垃圾填埋场火炬将减少全球温室气体排放总量的约1%。 4. HQP 的培训和组建：DG 计划和我打算研究的技术需要经过培训的 HQP 来开发和操作这些复杂的流程。废物管理、反应堆设计和运行是未来的挑战，该总干事将准备和培训多才多艺的人才来应对这些挑战。
