摘要
采用浸渍法制备醋酸锌-活性炭催化剂,研究了普通浸渍和超声波浸渍制备醋酸锌-活性炭催化剂,通过优化实验,得出超声波浸渍的适宜条件是:浸渍时间30min,超声波频率28MHz,浸渍温度45℃.在此条件下制得的催化剂较普通浸渍制得的催化剂醋酸锌含量提高了7%,比表面积提高了约30%.活性测试结果表明,超声波浸渍制备的催化剂活性较普通浸渍制得的催化剂活性显著提高,其中在180℃时活性提高了约34.54%.
This article use immersion method acetate zinc, studied general immersion method and to make catalyst using active carbon supported ultrasonic immersion method respectively, and got the optimum conditions of ultrasonic immersion method： dipping time 30 min, sound fre- quency 28 MHz, soaking temperature 45 ℃. The zinc acetate content of the catalyst made in this condition has raised 7% and specific surface has raised 30% compared to the catalyst made in general immersion method. Experimental results reveal that the catalyst made in ultrasonic immersion method has remarkable improvement compared to the catalyst made in general immersion method, and the catalyst activity improved about 34.54 at 180℃.
