柱撑黏土在加氢脱硫中的应用研究

摘要

以柱撑黏土为载体,制备了W-Ni/Al-Fe-PILC和W-Ni/Al-PILC加氢脱硫催化剂,对FCC汽油进行加氢脱硫研究.用50 mL微型固定床反应评价装置.结果表明:W-Ni/Al-Fe-PILC和WNi/AlPILC两种催化剂具有较好的加氢脱硫效果,脱硫率达到75％以上.最佳的工艺条件为反应温度340℃,反应压力6.0 MPa,空速为4.0 h-1.%Mo-Ni/Al-Fe-PILC and Mo-Ni/Al-PILC hydrodesulfurization catalysts were prepared by PILM used as the carrier and the catalyst effect were evaluated in 50 mL fixed-bed reactor, for the FCC gasoline hydrodesulfurization. The results show that Mo-Ni/Al-Fe-PILC and Mo-Ni/Al-PILC had good hydrodesulfurization effect, the desulphurization rate reaches more than 75% , the optimum technological conditions for the reaction are that temperature 340 XI,reaction pressure 6.0 Mpa, airspeed 4.0 h-1.
