PI: Park, Ah-HyungProposal Number: 1336567Institution: Columbia UniversityTitle: Sustainable Co-generation of Hydrogen and Biochar from Biomass via a Novel Alkaline Thermal TreatmentThis project investigates biomass conversion to COx-free hydrogen (H2) with co-generation of biochar via a novel alkaline thermal treatment. CO and CO2, commonly produced during pyrolysis, will react with the alkali metal hydroxide to form stable metal carbonates leading to gaseous product that is free of carbon. Thus, the produced hydrogen can directly be used in fuel cells for electricity generation without subsequent gas cleanup/upgrade steps. In this study, both non-catalyzed and catalyzed reactions of biomass and hydroxide will be investigated to optimize and evaluate the overall sustainability of the proposed biomass conversion scheme. If successful, this transformative approach to biomass conversion will provide an important stepping stone for the development of a sustainable energy pathway based on carbon-neutral bioenergy.The fundamental reaction kinetic and mechanistic studies will reveal important reaction pathways for forming a carbon-free hydrogen stream from various biomass feedstocks. The findings from this complex solid-solid reaction scheme involving in-situ carbon capture will not only provide the proof-of-concept of this novel biomass conversion technology but also the fundamental basis for other biomass conversion technologies. Ultimately, if successful, this technology will advance the field of sustainable energy generation by allowing the traditional energy consumers to be able to engage in the decision making process in energy production or even become energy producers themselves. The main technological benefits of the proposed biomass-to-H2 scheme include the co-generation of H2 and biochar, significant reduction in carbon emissions with the potential to be carbon-negative, no need for additional gas cleanup steps, and a simplified reactor design.The team?s educational and outreach activities include: to promote the international research and educational collaborations in the proposed research area; to motivate K-12 students, particularly female and minority students, to pursue a career in science and engineering; to provide academic research experience for both graduate and undergraduate students; and to enable the development of a new curriculum reflecting an increasing interest in green energy and environmental issues.

PI：Park, Ah-Hyung 提案编号：1336567 机构：哥伦比亚大学 标题：通过新型碱性热处理从生物质中可持续联产氢气和生物炭 该项目研究通过新型碱性热处理将生物质转化为不含 COx 的氢气 (H2)，并联产生物炭。通常在热解过程中产生的CO和CO2将与碱金属氢氧化物反应形成稳定的金属碳酸盐，从而产生不含碳的气态产物。因此，产生的氢气可以直接用于燃料电池发电，无需后续的气体净化/升级步骤。在本研究中，将研究生物质和氢氧化物的非催化和催化反应，以优化和评估所提出的生物质转化方案的整体可持续性。如果成功，这种生物质转化的变革性方法将为开发基于碳中性生物能源的可持续能源途径提供重要的垫脚石。基本反应动力学和机理研究将揭示从各种生物质原料形成无碳氢气流的重要反应途径。这种涉及原位碳捕获的复杂固-固反应方案的研究结果不仅将为这种新型生物质转化技术提供概念验证，而且还为其他生物质转化技术奠定了基础。最终，如果成功，这项技术将推动可持续能源发电领域的发展，让传统能源消费者能够参与能源生产的决策过程，甚至自己成为能源生产者。拟议的生物质制氢方案的主要技术优势包括联产氢气和生物炭、显着减少碳排放并有可能实现负碳、无需额外的气体净化步骤以及简化的反应器设计。该团队的教育和外展活动包括：促进拟议研究领域的国际研究和教育合作；激励 K-12 学生，特别是女生和少数族裔学生，从事科学和工程领域的职业；为研究生和本科生提供学术研究经验；并开发新课程，反映人们对绿色能源和环境问题日益增长的兴趣。
