柠檬酸对负载型磷化镍催化剂加氢脱硫性能的影响
, PP. 1246-1251
Keywords: 磷化二镍,二氧化钛,三氧化二铝,加氢脱硫,柠檬酸,络合剂
Abstract:
？采用溶胶-凝胶法制备了tio2-al2o3复合载体,以柠檬酸(ca)为络合剂采用浸渍法制备了ni2p负载的tio2-al2o3复合载体催化剂,并用x射线衍射(xrd)、n2吸附比表面积(bet)测定、热重-差热分析(tg-dta)、程序升温氢还原(h2-tpr)和透射电子显微镜(tem)技术对催化剂的结构和性质进行了表征,考察了加入ca对ni2p/tio2-al2o3催化剂二苯并噻吩(dbt)加氢脱硫(hds)性能的影响。结果表明,适量的ca可以丰富催化剂的孔道,提高催化剂的比表面积,使催化剂具有更好的孔结构、更高的金属活性组分分散度和更均一的活性组分尺寸。ca的引入可以减弱金属与载体之间的相互作用,显著降低ni和p前驱体的还原温度,促进ni-p-o活性相前驱态的生成。在360℃、3.0mpa、氢油比500(体积比)、液时体积空速2.0h-1的条件下,反应4h时二苯并噻吩转化率达到99.5%。在48h内二苯并噻吩转化率可稳定在95.0%左右。
