Two types of membrane reactors have been constructed in order to evaluate the influence of membrane reactor configuration on the performance of the dehydrogenation of ethylbenzene in a porous alumina membrane reactor. The type I construction combine reaction and separation in the same space. The type II configuration is comprised of three parts, i.e., reaction prior to separation, reaction and separation, and reaction after separation. The results showed that the overall yield of styrene in Type I is only 4% higher than that of the fixed bed reactor at 893 K, while 11 % enhancement in yield to styrene was obtained with Type II through optimizing the reaction conditions. 相似文献

The oxidative dehydrogenation of ethylbenzene to styrene on various oxide catalysts has been investigated. The catalysts examined are classified into six types, considering their catalytic behavior. In general, acidic catalysts show high selectivity. The most effective catalyst has been found to be the SnO2-P2O5 catalyst prepared from Sn(OH)2 and phosphoric acid. The effects of partial pressures and reaction temperature have been studied and suitable reaction conditions for the SnO2-P2O5 catalyst have been determined. 相似文献

The authors present analysis of variants of using low-potential heat, which improve the efficiency of steam gas-fired boilers,
air heating, and cleaning waste gases from toxic emissions in thermal machines. In order to achieve a more complete moisture
removal from combustion products, an upgraded design of a contact heat recovery unit is proposed equipped with a drip pan
with cooled packing.
