In situ NMR imaging studies of the drying kinetics of porous catalyst support pellets

Article Abstract:

The process of drying alumina and titania porous catalyst support pellets incorporated with various liquid spatial distribution was studied using the proton nuclear magnetic resonance imaging technique. In the drying process, four regions were differentiated in a liquid-filled porous solid particle. The NMR microscopy facilitated the observation of macroscopic liquid transport in porous materials by monitoring the changes in spatial distribution of liquid content.

Methane and carbon dioxide hydrate formation in water droplets: Spatially resolved measurements from magnetic resonance microimaging

Article Abstract:

(Super 1)H magnetic resonance microimaging is used to probe both methane and carbon dioxide hydrate formation processes inside dispersed water droplets. Results presented on the growth of hydrates in droplets suggest that different approaches could be used to control hydrate formation or prevention.
