TiO_2对Ni_2P催化剂加氢脱硫性能的影响

Effect of TiO_2 on hydrogenation desulfurization performance of Ni_2 P catalyst

以DBT为模型化合物,研究了不同的钛引入量对Ni2P催化剂加氢脱硫性能的影响。通过表征发现少量钛的引入影响了Ni2P前体的还原性能;钛的引入提高了Ni2P催化剂的加氢性能,随着钛引入量的增加,加氢选择性和加氢脱硫活性出现先增加后降低的趋势,当Ti/Ni=0.03时,加氢脱硫活性最高。

Based on DBT as model compound,hydrodesulfurization(HDS)performance was investigated on Ni2 P catalyst with the different amount of titanium.The result showed that the Ni2 P reduction performance is significantly influenced and hydrogenation performance is improved by a small amount of titanium added.Hydrogenation selectivity and HDS activity increase to the highest and then decrease with the increasing amount of titanium.When the Ti/Ni molar ratio is 0.03,HDS activity is the highest.
