摘　　要：ZSM-5 zeolite membrane reactor was used in ethylbenzene dehydrogenation to styrene under the circumstances of commercial production.The experimental results indicated that the conversion of ethylbenzene in the membrane reactor increased with increasing pressure of the membrane tube.Using the inert sweep gas instead of vacuumizing, the result of long term steady operation under the same condition showed that the selectivity of styrene increased and the conversion of ethylbenzene in the membrane reactor increased by 7.52% in comparison with the fixed-bed reactor.ZSM-5 zeolite membrane reactor was used in ethylbenzene dehydrogenation to styrene under the circumstances of commercial production.
