在滴流床反应器中，在ＳＴ０６型镍催化剂的作用下，进行了４－硝基二苯胺液相连续加氢还原制ＲＴ培司（４－氨基二苯胺）的试验。考察了反应温度、压力、停留时间以及初始物料浓度等对反应的影响，得到的适宜工艺条件为：压力２．０ＭＰａ，反应热点温度１６０℃左右，进料重量百分浓度１５％，气液摩尔比３．５～４．０，停留时间大于等于６０ｍｉｎ，在此条件下，４－硝基二苯胺转化率大于９９％，４－氨基二苯胺摩尔收率大于９７％。同时，考察了催化剂的寿命，经１０００ｈ运转，催化剂活性和选择性没有明显变化。In a trickle-bed reactor, the reaction rule of continuous hydrogenation of 4-nitrodiphenylamine to produce 4-aminodiphenylamine was studied. By using the ST06 Ni catalyst, under the following optimum conditions: pressure 2. 0 MPa, temperature 160℃, residence take of liquid≥ 60 minutes, gas-liquid mole ratio 3. 5～4. 0 and the concentration of the feed 15%, the conversion of 4-nitrodiphenylamine is more thsn 99%, and the yield of 4-aminodiphenylamine is more than 97%(mole). The catalyst was tested for about 1 000 hours, and the result shows thst its activity and selectivity hsve remained the same.
