Reduction in nitrogen oxides (NOx) emissions from high temperature combustion processes under fuel-lean conditions continues to be a priority research area for Imperial Oil and a challenge for the energy industry. Selective catalytic reduction (SCR) is possible with metal oxides and zeolites. There is still the need to identify catalytic materials that are efficient in reducing NOx to environmentally benign nitrogen gas at temperatures lower than 300 degrees C in the presence of oxygen and moisture. Metal-organic frameworks (MOFs) are an emerging class of highly porous materials with unique physical and chemical properties. While studies to date focused on their synthesis and characterization, their full potential as promising materials in catalysis and gas conversion for applications in the chemical/energy sectors is not yet realized. We aim to evaluate the performance of MOFs containing iron and organic linkers of various oxidative potential in the SCR of NOx. These materials passed bench scale synthesis and are marketed on mass scales by BASF. The catalytic activity of these materials will be tested under industrially-relevant conditions of pressure, temperature, NOx levels and gas phase water content. This research is significant because it presents opportunities for evaluating emerging catalytic materials for potentially game-changing replacements to existing NOx scrubbers that will help Imperial Oil meet strict emission regulations while cutting costs in NOx SCR operations at their facilities.**

在燃油叶子条件下，高温燃烧过程中的氮氧化物（NOX）排放量仍然是帝国石油的优先研究领域，并且对能源行业的挑战是挑战。 对于金属氧化物和沸石，可以选择性催化还原（SCR）。 在氧气和水分存在下，在低于300摄氏度的温度下，仍需要鉴定有效地将NOX降低到环境良性氮气的催化材料。 金属有机框架（MOF）是一类新兴的高度多孔材料，具有独特的物理和化学特性。尽管迄今为止的研究集中在其综合和表征上，但尚未实现它们作为化学/能量部门应用的催化和气体转化中有希望的材料的全部潜力。 我们旨在评估NOX SCR中含有各种氧化潜力的铁和有机接头的MOF的性能。 这些材料通过了基准尺度的合成，并通过巴斯夫以质量尺度销售。 这些材料的催化活性将在与工业相关的压力，温度，NOX水平和气相水含量的条件下进行测试。 这项研究很重要，因为它为评估新兴的催化材料提供了机会，以将可能改变游戏的替代者替换为现有的NOX洗涤器，这将有助于帝国石油符合严格的排放法规，同时在其设施的NOX SCR运营中削减成本。** **
