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，燃烧和排气排放了约650万吨二氧化碳当量。应该设想一个解决这个问题的办法。这项发现基金（DG）的长期目标是开发一种小规模的高停留时间非催化甲烷热解技术，旨在最大限度地提高氢和碳的产量，并消除燃烧，显著减少加拿大石油工业的温室气体排放。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。最后的反应产生水、固体碳和能量。目前，这个高排放行业还没有解决方案，因为GtL技术要么共同产生二氧化碳，要么不能完全转化溶液气体，无论如何都必须燃烧。此外，基于熔盐的最新技术受到污染问题的困扰，其特点是资本支出（CAPEX）很高。本课程的目标是：1。了解非催化热解反应的基本原理。建立天然气热解动力学模型，评估组分和工艺参数对产氢率的影响，探索减少反应器壁上碳生成的策略。此外，这项研究的范围不仅限于天然气，还包括其他能源，这些能源要么被燃烧，要么不能正确捕获相关的二氧化碳，如垃圾填埋气和沼气。2. 实施电气化，即感应加热，以开发一个强化的过程，最终可以生产氢气用于能源或其他能源分子，如甲醇3。设置环境-技术-经济过程优化的框架。通过结合技术经济分析和生命周期评估（LCA）指标，早期阶段工艺的设计真正得到优化，因为它结合了低成本和低环境后果。这个DG研究项目的主要影响将是1。新技术途径：这项研究将开发新的反应器设计，并设想一种处理天然和生物气体以产生氢气的新方法。2.经济：加拿大有3000多口油井，如果考虑到美国的油井，这个数字还会增加。这项新技术从未针对减少燃除进行过研究和优化，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：消除气体和垃圾填埋燃烧将减少全球温室气体排放总量的约1%。4. HQP的培训和形成：DG项目和我要学习的技术需要训练有素的HQP来开发和操作这些复杂的过程。废物管理，反应堆设计和操作是未来的挑战，这个DG将准备和培训多才多艺的人来解决这些问题。
