Реферат:
The1H nuclear magnetic resonance (NMR) microimaging is employed to study the mass transport processes in porous materials, including individual catalyst support pellets and beds comprised of porous grains. Drying and adsorption are investigated by detecting the temporal evolution of the one-dimensional spatial profiles or two-dimensional maps of liquid content without interrupting the process under study. The characteristic features of these processes, such as the main mechanisms and the limiting stages of mass transport, and some factors which can alter the efficiency of mass transport are considered. The problems associated with the relaxation weighting of the NMR signals, often unavoidable for liquids permeating mesoporous solids, and the possibilities to overcome these problems are discussed.
