Abstract
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.

NMR of Edible Oils
NMR spectroscopy is one of the most informative techniques for the study of structure, composition and dynamics of matter. One of the many thousands of applications of NMR spectroscopy is in the study of edible oils. Plant and animal oils are composed of complex mixtures of fatty acid tri-esters of glycerol. The fatty acid moieties are generally straight chains of 16 - 24 carbons in length with various degrees of unsaturation. In natural oils the double bonds are all cis-. Fatty acids with trans- double bonds are usually the result of food processing. The double...
