These results indicated that a well structured anatase TiO2 was obtained by impregnation method under 500℃. Flow rate, in the activity test, could be neglected for mass transfer effects. As a matter of fact, relative humidity played the most important role in this reaction. The highest removal efficiency was obtained while relative humidify of 56.8%. Water molecules are sources of ; however, excessive water molecules could inhibit reactions by competing activity sites with organic containments. In the regeneration test, photocatalyst could be reactivated through a running water vapor with UV light illumination process.
研究结果指出,以含浸法制备之触媒於500℃锻烧下,具有良好的锐钛矿晶体结构;另外在活性测试的部份,流量的增加,污染物之去除效果不受影响,所以本实验选择以200ml/min之流量可忽略质传影响;湿度扮演重要的角色,当RH=56.8%时去除效率最高,主要因水气是产生氢氧自由基的主要来源,但是过多之水气可能与有机物竞争触媒表面上的活性位置,因而抑制反应的进行;初使浓度对去除率之影响中得知,初使浓度的高低不会影响触媒对有机物的催化能力,实验使用之触媒量适合催化200~250ppm之有机物,可藉由增加触媒量提高对有机物之催化能力;此外再生的测试,触媒可经由连续曝水及紫外光的照射,使触媒恢复原有的活性,可再次利用。

MMA is produced by the method of acetone-cyanhydrin mainly in our country. The synthetic route is complex, the technical line is long, and the yield is low with high cost after many steps. Hydrocyanic acid is used as raw material, the treatment of numerous waste acid is difficult . Furthermore, concentrated sulfuric acid consumed in this method corrodes equipments and pollutes the environment seriously.
我国MMA的生产以丙酮腈醇法占主导地位,合成路线复杂,生产工艺长,多步反应后产率低,成本高,其采用有剧毒的氢氰酸为原料,产生大量难于处理的废酸,所消耗的浓硫酸对设备腐蚀性大,对环境污染严重,因此开发新的MMA工艺路线很有必要。
