摘要:
采用超临界CO2技术制备MoNi/介孔TiO2加氢脱硫催化剂(MoNi/TiO2-SUP)。采用X线衍射仪(XRD)、N2吸附-脱附和透射电子显微镜(TEM)对催化剂的结构进行表征。以二苯并噻吩(DBT)为含硫模型化物,考察催化剂的加氢脱硫性能。结果表明:MoNi/TiO2-SUP催化剂较浸渍法制备的催化剂(MoNi/TiO2-IMG)具有更高的活性组分分散度; MoNi/TiO2-SUP催化剂的单位活性更高,并且直接脱硫的比例较高,有利于燃油的辛烷值(十六烷值)保留。
Abstract:
The MoNi/mesoporous TiO2 hydrodesulfurization(HDS)(MoNi/TiO2-SUP)catalyst was prepared with the supercritical carbon dioxide.The sample was characterized by X-ray diffraction(XRD),N2 adsorption-desorption, and transmission electron microscopy(TEM).The hydrodesulfurization performance of the catalysts was evaluated in a fixed-bed microreactor using dibenzothiophene(DBT)as the model compound.The results showed that the MoNi/TiO2-SUP catalyst had higher dispersion of activity component compared with the MoNi/TiO2-IMG catalyst.The MoNi/TiO2-SUP catalyst exhibited good catalytic activity,and the proportion of direct desulfurization route was relatively high which benefited the retention of the octane number(cetane number)of fuel oil.
