摘　　要：在低还原温度下程序升温还原法制备了Ni2 P/MCM-41催化剂，并采用H2-TPR、TG-DTG、XRD、BET、XPS等手段对制备的催化剂进行了表征，考察了还原温度对活性相Ni2 P形成以及催化剂二苯并噻吩HDS性能的影响。结果表明，在210-390℃下还原得到的催化剂活性相为单一的Ni2 P相；在390℃下还原得到的催化剂具有最高的二苯并噻吩HDS活性，在反应温度340℃、反应压力3.0 MPa、氢/油体积比500、质量空速（WHSV）2.0 h-1的条件下二苯并噻吩HDS转化率达到99.0%。The Ni2 P/MCM-41 catalysts was prepared at low reduction temperature by temperature programmed reduction. The catalyst was characterized by H2-TPR, TG-DTG, XRD, BET, and XPS. The effects of reduction temperature on formation of the active Ni2 P phase and HDS performance of the catalysts were studied. The results showed that a pure Ni2 P phase can be obtained with samples reduced at low reduction temperature range of 210 -390 ℃. The catalyst obtained at reduction temperature of 390 ℃ exhibited the highest HDS activity. At a reaction temperature of 340 ℃, pressure of 3. 0 MPa, H2/oil volume ratio of 500, and weight hourly space velocity （WHSV） of 2. 0 h-1, the DBT HDS conversion reached to 99. 0%.
