摘要：

An experimental study of the separation of an equal amount of p- and m-xylenes on silicalite using carbon dioxide as the carrier was performed. The results showed that the operations in the gaseous phase of carbon dioxide offered a better separation efficiency over those at supercritical conditions. The effects of temperature, pressure, and flow rate on the effectiveness of separation were also examined. It was found that, for a pulse of 1.0 cm3of xylene isomers and 39.5 g of silicalite, the most appropriate operating conditions were temperature around 358 K, pressure of 47.6 atm, and flow rate of 15.0 cm3/min. © 1990, American Chemical Society.
