Study on catalytic activity of Ni₂P/HZSM-5 in thiophene hydrodesulfurization

A series of supported Ni₂P catalysts on HZSM-5 were prepared via TPR. Thiophene HDS was selected as a model reaction to study the influences of Ni loading and initial Ni/P mole ratio. Ni₂P phase was formed on the support of HZSM-5. Ni₂P/HZSM-5 catalysts had high activity and excellent stability in thiophene HDS reaction. The preparation factors had great effects on the activity and stability of the thiophene HDS reaction. With increasing Ni₂P loading and the initial P/Ni mole ratio, the activity and stability of the Ni₂P/HZSM-5 catalyst increased firstly and then decreased. Results of a study on the effect of ration conditions on thiophene HDS performance were presented.
