✦ Synopsis

The two phase model of a freely bubbling gas-fluidised bed in which chemical reaction is occurring has been described in detail by Partridge and Rowe. It is based on knowledge of the physical behaviour of the system and of the chemical kinetics. The isomerisation of butene-1 to a mixture of cis-and truns-butene-2 is an ideal reaction with which to test the model for it is comparatively simple kinetically and reasonably well understood.

The paper describes the kinetics and how the data was obtained. Experiments are described in which varying mixtures of butene-1 and inert nitrogen were passed through a bed of silica-alumina catalyst which it fluidised and in which the composition of the exit gas was determined.

The results are described very well by the proposed model and confirm several of its details.
