✦ Synopsis

In a fluidized bed reactor the thermal decomposition of sodium hydrogen carbonate into sodium carbonate, carbon dioxide and water was carried out in continuous operation. The fluid dynamical structure of the bed was characterized by measurements with capacitance probes. Signal processing was carried out by a process computer.

Data for bubble volume fraction, bubble rising velocity and bubble diameter have been obtained in the presence and absence of a chemical reaction. The influence of the reaction on the fluid-dynamical structure is significant.
