Radiotracer Investigations of the Dynamics of Gas Flow through Packed Bed

Radiotracer investigations of the gas flow dynamics in the catalytic bed chemical reactor have been carried out. 79Kr has been used as a radiotracer. The coefficient characterizing the inflow velocity profile of gas on the bed determined by a thermoanemometric method, has been correlated with the model parameters of the gas flow within the packed bed. For modelling of the gas dynamics within the catalyst layer, dispersion model and -plug-flow and stirred tank models in series have been applied.
