CuO/ZSM-5/PSSF was synthesized by a combined wet lay-up papermaking, secondary growth and chemical vapor deposition (CVD) method for the catalytic oxidation of ethyl acetate in the fixed bed reactor. Ethanol and acetaldehyde are found during the oxidation and 3 wt% CuO/ZSM-5/PSSF catalyst exhibited the best performance with 90% conversion of 1500 ppm ethyl acetate at 254 °C with GHSV of 15,000 h−1, and the CuO/ZSM-5/PSSF exhibits low byproducts selectivity compared to granular CuO/ZSM-5 catalyst. Furthermore, the 3 wt% CuO/ZSM-5/PSSF catalyst exhibits a high stability after being used at 262 °C for 48 h.

化学气相沉积法在涂覆在不锈钢纤维上的CuO / ZSM-5沸石膜上催化乙酸乙酯的氧化

CuO / ZSM-5 / PSSF是通过湿法造纸,二次生长和化学气相沉积(CVD)的方法合成的,用于固定床反应器中乙酸乙酯的催化氧化。在氧化过程中发现了乙醇和乙醛,其中3 wt%的CuO / ZSM-5 / PSSF催化剂表现出最佳的性能,在254°C时GHppm为15,000 h -1时1500 ppm乙酸乙酯的90%转化率,以及CuO / ZSM与颗粒状CuO / ZSM-5催化剂相比,-5 / PSSF的副产物选择性低。此外,3 wt%的CuO / ZSM-5 / PSSF催化剂在262°C下使用48小时后显示出高稳定性。
