- 摘要:
- 本文以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影响，通过表征发现少量钛的引入显著影响了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（HDS）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 compounds, hydrodesulfurization (HDS) performance was investigated on Ni2P catalyst with the different amount of titanium. The results showed the Ni2P reduction performance was significantly influenced and hydrogenation performance was improved by a small amount of titanium added. Hydrogenation selectivity and HDS activity increase maximum and then decreased with the increasing amount of titanium. When the Ti/Ni molar ratio is 0.03, HDS activity is the highest.
