A mobile, low-field nuclear magnetic resonance (NMR) sensor for onboard, inline detection of catalytic fines in fuel oil in the shipping industry is presented as an alternative to onshore laboratory measurements. Catalytic fines (called cat fines) are aluminosilicate zeolite catalysts utilized in the oil cracking process at refineries. When present in fuel oil, cat fines cause abrasive wear of engine parts and may ultimately lead to engine breakdown with large economical consequences, thereby motivating methods for inline measurements. Here, we report on a robust, mobile, and low-cost (27)Al NMR sensor for continuous online measurement of the level of catalytic fines in fuel oil onboard ships. The sensor enables accurate measurements of aluminum (catalytic fines) in ppm concentrations in good agreement with commercial laboratory reference measurements.
本文介绍了一种用于航运业燃油中催化细粉船上在线检测的便携式低场核磁共振（NMR）传感器，作为岸上实验室测量的替代方案。催化细粉（简称猫粉）是炼油厂石油裂化过程中使用的铝硅酸盐沸石催化剂。当存在于燃油中时，猫粉会导致发动机部件的磨料磨损，并最终可能导致发动机故障，造成巨大的经济后果，因此推动了在线测量方法的发展。在此，我们报告了一种坚固、便携且低成本的（27）Al NMR传感器，用于船上燃油中催化细粉水平的连续在线测量。该传感器能够准确测量ppm浓度的铝（催化细粉），与商业实验室参考测量结果高度一致。
