Effect of the incorporation of ETS-10 into alumina on metal-support interactions and hydrodesulfurization activity

A novel catalyst of Ni,W-surface-Ti-rich-ETS-10/Al 2 O 3 : Its role and potential of HDS performance for steric hindered sulfur compound 4,6-DMDBT

“…The first one was attributed to WO 3 phase from 40.5 eV ranges to 35.3 eV and the second one was attributed to WS 2 phase from 35.3 eV ranges to 29.0 eV. The sulfidation degree of oxidic W species was defined as the ratio of W 4+ (WS 2 ) to the sum of W 4+ (WS 2 ) and W 6+ (WO 3 ) [25], where the content of WS 2 and WO 3 were obtained from integration area on the XPS W 4f spectra of the catalysts. After the calculation, the sulfidation degree of NiW-ETS/Al 2 O 3 and NiW-ATS/Al 2 O 3 are 70% and 69% respectively.…”

“…In our previous works, ETS-10 supported NiW catalyst exhibited high HDS and HDA activity for a FCC diesel feed hydrotreating (sulfur content 1052 g/g) [23][24][25][26]. In our recent report, the surface-Ti-rich-ETS-10 was prepared by alkali-treatment process to remove Si atoms from the frameworks of ETS-10 [27].…”

Effect of Divalent Tin on the SnSAPO-5 Molecular Sieve and Its Modulation to Alumina Support To Form a Highly Efficient NiW Catalyst for Deep Hydrodesulfurization of 4,6-Dimethyldibenzothiophene

“…The performance and selectivity of HDS is strongly influenced by the support of catalysts. − To obtain highly active catalysts, acidic supports are some of the attractive directions for improving the performance of HDS catalysts, − such as ETS-10, Y, β, SBA-15, and AlPO 4 -5. Bej et al enhanced the catalytic activity of 4,6-DMDBT HDS by introducing other additives, such as fluorine, phosphorus, and zeolite, into alumina .…”
