NWaste2H2- H2 Production by Reforming Bio-methane with Nitrogen Rich Waste Streams

N2 H2项目旨在证明减少能源需求和相关温室气体（CO2，在AD工厂和废水处理厂（WWTP）厌氧消化生产沼气的N2 O排放量同时，在英国，通过重整可再生沼气生产清洁能源载体氢气可以经济地实现。该项目汇集了来自AD的专家研究人员团队，为期2年，该项目的合作伙伴包括利兹三所工程学院的废物处理（Camargo-Valero）、氢气生产（Dupont）和能源系统（Cockerill），以及污水处理厂、AD研究、氢气生产行业、英国市和郡议会的工业和外部合作者，以及印度、中国、泰国和马来西亚的学术合作伙伴，他们是该项目科学顾问委员会的成员。双方的共同努力将提供详细的工艺模型，英国范围内的技术部署模型，考虑到工艺下游产生的H2的不同用途，经济评估和综合H2生产的LCA，来自厌氧消化和废水处理厂的厌氧消化的沼气和富氮废物流。该项目的资金将用于雇用一名博士后助理18个月的费用，以及通过利兹大学生物能源博士培训中心资助的一名博士生的实验室费用，以及在生物能源和氢的世界会议上介绍这项工作的传播和旅行费用。所提出的技术背后的前提是利用将富氮有机共进料重整为氢气和氮气，二氧化碳作为副产物，这允许将大量废物流从AD/废水处理厂的脱氮阶段转移。蒸汽重整和自热重整的催化过程将作为潜在的H2生产路线进行研究。目前，在WWT中，亚硝酸盐溶液的反硝化代表了非常显著的资本和能量负担，这导致显著的一氧化二氮（N2 O）气体排放，而在100年的时间范围内，N2 O的全球变暖潜力大约是CO2的300倍。NH3 2 H2工艺不仅必须表现出向氢气的高转化率，而且还必须表现出向氮气的高转化率，以便显著地转移来自脱氮步骤的富N废物流。

The NWaste2H2 project aims to demonstrate that reducing the energy requirements and the associated greenhouse gas (CO2, N2O) emissions of biogas production at anaerobic digestion at AD plants and wastewater treatment plants (WWTP) whilst producing the clean energy vector hydrogen from reforming of the renewable biogas can be effected economically in the UK.This project brings together for 2 years a team of expert researchers in AD from wastes (Camargo-Valero), H2 production (Dupont) and energy systems (Cockerill) across three Engineering schools at Leeds, as well as industrial and external collaborators in the WWTP, AD research, H2 production industry, UK City and County Councils, with academic partners in India, China, Thailand and Malaysia who are members of the Scientific Advisory Board for the project. The combined efforts will deliver detailed process model, UK-wide technology deployment model considering the different uses of the H2 produced downstream of the process, economic evaluation and LCA of integrated H2 production from biogas and Nitrogen-rich waste streams from anaerobic digestion at Anaerobic Digestion and Wastewater Treatment plants. Funding for the project will provide for the costs of employment of a postdoctoral assistant for 18 months, as well as the laboratory expenses for a PhD student funded through the Centre for Doctoral Training on Bioenergy at The University of Leeds, and the dissemination and travel costs associated with presenting the work at world conferences on bioenergy and hydrogen.The premise behind the proposed technology is to exploit the ability of reforming nitrogen rich organic co-feeds to hydrogen and nitrogen gas, with carbon dioxide as co-product, which allows diverting a large waste stream from the denitrification stage at AD/wastewater treatment plants. Both catalytic processes of steam reforming and autothermal reforming will be investigated as potential H2 production routes. Denitrification of digestate liquor at WWT currently represents a very significant capital and energy burden which results in significant nitrous oxide (N2O) gas emissions, when N2O has a global warming potential roughly 300 times that of CO2 over a 100 years horizon. The NWaste2H2 process will have to show high conversions not just to hydrogen gas but also to nitrogen gas in order to significantly divert N-rich waste streams from the denitrification step.
