A method for evaluating catalysts in the reaction of hydrocarbon with catalyst deactivation has been investigated by the use of the isomerization reaction of ethylene oxide over silica-alumina catalysts of different compositions and properties. Because the coke deposition had a large influence on the main reaction as an inhibitor, it was not an appropriate method for evaluating the catalytic strength from the main reaction only. The over-all effective catalytic strength with the inhibition reaction taken into account was therefore defined in terms of <I>r</I><SUB>A0</SUB>α<SUB>C</SUB>/<I>r</I><SUB>C0</SUB>α<SUB>A</SUB> as a function of initial rate and deactivation coefficient. The evaluation of catalyst was carried out by this value. After investigation of its adaptability, there was a good correlation between this value and catalyst life, total amount of acetoaldehyde product formed during the catalyst life. It became clear that this value permits a kinetic evaluation of the catalyst.
