Abstract In This paper,Al\-2O\-3 membrane was prepared by the method of Sol\|Gel and was used in the reaction of diethylbenzene dehydrogenation.Through the change of temperature��LSV��purge gas rate��times of coating film get the results that the membrane reactor is better than fixed bed reactor.In a wide temperature range,the conversion and selectivity of membrane reactor are higher than fixed bed reactor;in membrane reactor,conversion and selectivity decreased with the increase of LSV;when the purge gas rate is lower than 60mL/min,conversion and selectivity increased with the increase of purge gas rate;conversion and selectivity increased with the increase of times of coating film.
