摘要
以1,2,4-TCB为材料,研究了不同的处理方式对Pd／Fe催化剂脱氯稳定性的影响。结果显示:干燥处理会显著降低 Pd／Fe催化剂的活力,失活后的Pd／Fe经酸洗可恢复部分活力,保存在水中的Pd／Fe其催化活力也会逐渐降低,2d后会降至最初的1/5。
The stability of Pd/Fe in dechlorination of 1,2,4-trichlorobenzen is studied, And the result showed that the activity of Pd/Fe can be markedly deactivated after drying treatment,and it was partly restored by acid washing. Preserved in water can prolong the life the catalyzer but anyway it decline to 1/5 in 2 days.
