Experimental study on the optimum performance of an adiabatic MT reactor

The performance of an adiabatic MT reactor has been studied under various experimental conditions, using the reaction between hydrogen peroxide and sodium thiosulphate. Following the M‐section, consisting of a CSTR, the T‐section was made up of a large number of small stirred tanks in series. The same general condition for optimizing the MT model, that the reaction rate in the M‐section be a maximum, is shown to apply when maximizing the conversion for a given residence time as it was shown previously to apply when minimizing the residence time for a given conversion. Very good agreement is shown between theoretical and experimental results, confirming the superior results often obtained with an MT combination as compared with those given by a stirred tank or a tubular reactor under similar conditions. Bi‐stable steady states of conversion have been achieved and their effect shown on the performance of the combined reactor.
