PL-6At the same time, other exciting possibilities will clearly emerge. In particular, the possibilityto develop spatially resolved NMR thermometry techniques for the studies of heat transport inchemical engineering, including hot spots formation and evolution in catalysis, will bediscussed. Multinuclear imaging of solids can be useful for the direct visualization of, e.g.,transport of granular solids in various geometries including fluidized beds. Imaging ofmaterials comprising a solid finely dispersed in a porous solid matrix will be useful, forinstance, for mapping NaCl distribution in building materials, LiCl and other salts in selectivewater sorbents, etc.Another direction pursued in our studies is the combination of multinuclear MRI ofliquids (solutes) with that of solids. This approach appears to be promising for the in situstudies of the preparation of supported catalysts and composite water sorbents. During theimpregnation stage, transport of the solute (catalyst precursor, salt) can be visualized as itpermeates the porous support immersed in the impregnation solution. Imaging of the solidphase is helpful to evaluate the final distribution of a catalyst or salt after the pellet is dried.Comparison of the imaging results of the liquid and solid phases allows one to studyinteraction of the active component with the porous support and to assess its redistributionwithin the support during the drying stage.Acknowledgments.
