ETS-10 Modulation to Alumina Support and its Promotion for Hydrodesulfurization

Abstract

A composite support with ETS-10 stabilized in alumina, was firstly developed for hydrodesulfurization (HDS). It can impede inactive nickel spinel formation and favor more polymeric tungsten species formation, which facilitates the promotion effect of nickel on tungsten and leads to increasing activity in HDS of 4,6-DMDBT.

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

“…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].…”
