Macro-pore Volume Mesoporous Alumina: A Promising Support for Mo-Ni-P Catalyst in Hydrodesulfurization

摘要

Macro-pore volume mesoporous alumina (MMA) synthesized by secondary nano-assembly method was applied as support for Mo-Ni-P catalyst. The samples were characterized by mercury intrusion method, XRD, TEM, and SEM. They displayed simultaneously enough active sites and particular larger pores structure. By taking advantage of these properties, Mo-Ni-P MMA catalyst bearing high active species dispersion, good reducibility, and enhanced diffusibility compared with a commercial catalyst. It is prospected that the obtained MMA had a good potential as support for HDS catalysts.
