A mathematical treatment of the use of ultrasound in homogeneous and heterogeneous catalysis.
The possibility of increasing the effectiveness of a catalyst in the form of porous granules by artificially changing the activity profile of a catalytic reaction proceeding under non-steady-state conditions is shown. The results can also be used for the analysis of homogeneous reactions. Ultrasound can be used to generate the non-uniform concentration and temperature fields with time in the reaction mixture. Ultrasound can also be used for the activation and deactivation of the catalytic centres.
