AI Technical Summary
Existing technologies cannot achieve continuous, non-invasive, high spatial resolution monitoring of catalyst bed temperature distribution in hydrogenation reactions, which poses safety hazards, especially under high pressure conditions, and lacks the ability to dynamically track rapid temperature changes and provide early warning of temperature spikes.
By employing nuclear magnetic resonance imaging (NMR) devices, a quantitative correlation between NMR signal parameters and catalyst bed temperature is established. Combined with the intrinsic NMR signal of the catalyst support and the added temperature-sensitive material, non-invasive, high spatial resolution in-situ real-time monitoring of the catalyst bed is achieved, and time-domain analysis is performed for early warning of temperature spikes.
It enables non-invasive, high spatial resolution in-situ real-time monitoring of catalyst bed temperature, identifies hotspot locations and temperature gradients, provides multi-physics correlation analysis, and improves reaction safety and process optimization capabilities.
