Facile fabrication of Ni-based KIT-6 for adsorptive desulfurization

Syngas production from dry methane reforming over yttrium-promoted nickel-KIT-6 catalysts

“…3. The characteristic la3d structure of KIT-6 can be clearly observed, further confirming the successful synthesis of this ordered mesoporous material [31][32][33][34][35][36][37][38]. Highly ordered mesopores create a bi-continuous network of channels.…”

“…This peak disappeared for Ni,Y-modified samples, as a consequence of the calcination of KIT-6 at 600ºC. The peak at 1380 cm -1 can be ascribed either to the remaining presence of template molecules or to or the N-O vibration of the nitrates used in the impregnation [36]. Since this peak looks more intense for the Ni-Y modified catalysts, it can be therefore linked to the presence of support is shown in Fig.…”

“…Due to its high specific surface area and very particular pore size distribution, KIT-6 ordered mesoporous silica with Ia3d symmetric structure has been recently considered as support in the preparation of catalysts for various processes [31][32][33][34][35][36][37][38][39]. For example, Ni-KIT-6 were examined in pyrolysis of cellulose [39], Ni-La/KIT-6 catalysts were tested in CO2 reforming [38]; Ni-V/KIT-6, Ni-Ce/KIT-6, Ni-La/KIT-6 and Ni-Mn/KIT-6 in CO methanation [33]; Cu/KIT-6 for thiophene removal [35]; SO4 2− /Zr-KIT-6 for esterification of oleic acid [31]; and Ti/KIT-6 for epoxidation of cyclohexene [32].…”

Oxidative desulfurization of dibenzothiophene catalyzed by α-MnO2 nanosheets on palygorskite using hydrogen peroxide as oxidant

“…However, these alternatives are costly to reneries. 4 Therefore, several alternative approaches have been used, such as biodesulfurization, 5 selective adsorption, 6 extraction by ionic liquids 7 and catalytic oxidative desulfurization (ODS). [8][9][10][11][12] Catalytic ODS, as an alternative to the conventional HDS, has been considered a promising method for deep desulfurization technology because it can be carried out under mild conditions, such as relatively low temperature, pressure and cost of operation when compared with HDS, and can meet future environmental regulations for low-sulfur diesel.…”

Recyclable Cu(i)/ZrSBA-15 prepared via a mild vapor-reduction method for efficient thiophene removal from modeled oil

“…25 As it is known, the adsorptive process is generally conducted at room temperature; if the process of regeneration was conducted at quite high temperatures, it would have involved a lot of heat, which possibly would have led to a signicant deterioration of the structures and sintering/aggregation of the active metal species. 26,27 As a result, it is difficult for the process to operate. Besides, there is limited focus on studying the desulfurization performance over multiple adsorption-regeneration cycles.…”
