“Nanowire catalysts for ultra-deep hydro-desulfurization and aromatic hydrogenation”

Mesoporous zeolite-supported metal sulfide catalysts with high activities in the deep hydrogenation of phenanthrene

“…The high aromatic content in diesel fuel lowers the fuel quality and contributes to the formation of undesirable emissions in exhaust gases [1][2][3][4][5]. A solution to this problem is to saturate the aromatics by hydrogenation over conventional c-Al 2 O 3 -supported metal sulfide catalysts (CoMoS/c-Al 2 O 3 and NiMoS/c-Al 2 O 3 ) [5][6][7][8][9][10].…”

“…A solution to this problem is to saturate the aromatics by hydrogenation over conventional c-Al 2 O 3 -supported metal sulfide catalysts (CoMoS/c-Al 2 O 3 and NiMoS/c-Al 2 O 3 ) [5][6][7][8][9][10]. However, the deep saturation of aromatics over these types of catalysts is difficult because of their low catalytic activities [2,11].…”

Remarkably high performance of clew-like ZnO superstructure in reactive adsorption desulfurization

“…As is seen, among all adsorbents, sample Ni/ZnO-4h has the highest ZnO conversion of 54.8%. Furthermore, sample Ni/ZnO4h also shows a higher capacity than most of other Ni/ ZnO adsorbents with various types of ZnO reported before [35,36,[40][41][42]. It was widely recognized that the RADS activity and sulfur adsorption capacity were closely related to the structure of Ni/ZnO adsorbents, including the dispersion of active sites (such as metallic Ni 0 ) for C-S bond cleavage [43], and particle size of ZnO for sulfur storage [5,22].…”

“…Different nanostructured ZnO materials have been synthesized [33,34]. ZnO nanowires prepared by Gupta et al [35] were tested in the RADS reaction. The adsorbent exhibits a high RADS activity and a large sulfur capacity, which is attributed to the easy sulfidation of ZnO nanowires and the fast sulfur transfer from Ni x SZn y to ZnO nanowires.…”

Scalable production and applications of metal oxide nanowires.

“…The well-defined surface facets provide higher concentration of desired sites [12]. Especially, nanowire support undergoes less sintering than the conventional supports of bulk or spherical particles [7,13]. As shown in Figure 1 …”
