摘要: 以MCM-41为载体,采用一种简捷、温和法制备了负载型Ni2P/MCM-41催化剂。用H2程序升温还原(H2-TPR)、X射线衍射(XRD)、N2吸附比表面积测定(BET)和X射线光电子能谱(XPS)分析对催化剂进行了表征。以1%(质量分数)二苯并噻吩(DBT)的十氢萘溶液为原料,在连续固定床反应装置上,研究了初始Ni/P物质的量比对催化剂HDS活性的影响,并考察了催化剂的稳定性。结果表明,初始Ni/P物质的量比为1/2和1/3的前驱体,在390 ℃下还原时得到单一的Ni2P相。初始Ni/P物质的量为1/2时,得到的催化剂活性最好。在反应温度340 ℃、压力3.0 MPa、氢/油体积比500、质量空速2.0 h-1时,DBT的转化率接近100%。
