Summary: | The present disclosure relates to a method for treating a catalyst that is useful for producing mono-alkylaromatic compounds, the method comprises the steps of (a) contacting the untreated catalyst with water to produce water-contacted catalyst, and (b) drying the water-contacted catalyst with a drying gas without steam being formed at a temperature of less than 300° C. to produce a treated catalyst. The treatment is effective to improve the activity and catalyst selectivity. A process for producing a mono-alkylaromatic compound comprising such a catalyst treatment is also disclosed. |
