| 摘 要： | 在低还原温度下程序升温还原法制备了Ni2P/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Ni2P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Ni2P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%。

| Abstract: | The Ni2P/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 Ni2P phase and HDS performance of the catalysts were studied. The results showed that a pure Ni2P 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%. |
