摘要：Ni-Mo catalysts supported on hierarchically macro-mesoporous alumina were prepared and applied to the hydrodesulfurization (HDS) of dibenzothiophene (DBT). The alumina supports with different macroporous structures (either parallel macropores or interconnected macropores) were synthesized by two methods, hydrolysis of aluminum tri-sec-butoxide and dual-template approach. All hierarchically porous structured Ni-Mo/Al2O3 catalysts showed higher HDS activities when compared to a Ni-Mo/Al2O3 with only mesopores, which were mainly due to the enhanced diffusion by macropores. In particular, a dual-template derived catalyst with highly interconnected macropores and large porosity displayed the best activity, which remained stable during a long-term test of 100 h.
