Studies of Dehydrogenation of Ethylbenzene in Zeolite Membrane Reactors
摘要
Abstract
The catalytic dehydrogenation of ethylbenzene to styrene inzeolite membrane reactors was studies. The influence of the properties of the zeolite membranes on the dehydrogenation of ethylbenzene to styrene was investigated. The experimental results indicated that under the same conditions the conversion of ethylbenzene in the membrane reactor could increase 10%~16% and the selectivity of styrene could be enhanced by 3% to 5% in comparison with the fixed-bed reactor. The permselectivity of membranes was the important factor affecting the dehydrogenation of ethylbenzene to styrene. The bigger was the permselecitivity and permeation of the membrane, the higher is the conversion of ethylbenzene . In Fe-ZSM-5 zeolite membrane reactor, the conversion of ethylbenzene was highest in comparison with the Silicalite-1 and ZSM-5 membrane reactors. This is attributed to the catalytic action of Fe in the framework of Fe-ZSM-5 on the dehydrogenation of ethylbenzene. The separation factor (H2/C3H8) of above zeolite membrane reactors decreased a little after reaction. Fe-ZSM-5 zeolite membrane has good stability for the reaction.关键词
