Abstract: PP-123 Исследования потоков жидкостей, газов и сыпучих тел методом ЯМР томографии в катализе The flow of gases and water in the systems of different geometry was investigated using NMR microimaging. In most cases, the maps of spatial velocity distributions were constructed. The possibility of using thermally polarized gases to study flow was demonstrated using acetylene, propane, and butane. Gas , and water flow in the nonconsolidated bed composed of solid glass beads was characterized by the displacement NMR spectroscopy on the basis of pulsed-field-gradient-stimulated-echo NMR technique. It is demonstrated that Pulsed Field gradient NMR can be successfully employed to study motion of fine solid particles through the fixed bed reactors.
