Effects of HY addition on NiMoS active phase of NiMo(NH3) impregnated NiMo/Al2O3-HY and its role in 4,6-dimethyl-dibenzothiophene hydrodesulfurization

V-Promoted Ultrasmall Pd Nanoparticles Supported on V-KIT-6 for the Enhanced Catalytic Dehydrogenation of Perhydro-N-ethylcarbazole

“…In order to further understand the Pd–V interaction, and the potential trade-off between adsorption and desorption caused by the acidity of the support, NH 3 -TPD was used to investigate the acidic sites on the surface of KIT-6 and V-KIT-6. Figure d shows the NH 3 desorption peaks in the range of 100–250, 250–400, and 400–600 °C corresponding to the weak, medium-strong and strong acid centers, respectively. This is clearly due to the existence of VO x species on the surface, which leads to the appearance of a sharp peak of weak acid and a broad peak of strong acid.…”

Effects of pyrolyzing and phosphiding on dibenzothiophene hydrodesulfurization of MOF-derived Ni2P

“…This makes it particularly important to design and develop innovative catalysts with excellent HDS performance for academia and industry [2][3][4][5][6]. In addition to improving the activity of typical Al2O3-supported Ni (Co) -Mo (W) sulfide HDS catalysts, noble metals, metal phosphides, metal silicides, metal borides, and metal carbides have all been used as catalysts for HDS reactions [7][8][9][10][11][12][13]. Among them, Ni2P is considered as a promising alternative to conventional HDS catalysts because of its high hydrogenation activity, good stability, and strong tolerance to sulfur and nitrogen [14,15].…”
