静电纺丝法制备氧化钛-氧化石墨复合载体的加氢脱硫性能 Hydrodesulfurization performance of TiO
Novel TiO2 nanofibers(NF) and TiO2(NF)-graphene oxide (GO) supports were prepared by electro-spinning
and NiMo/TiO2(NF) and NiMo/TiO2(NF)-GO catalysts were obtained by incipient impregnation. The properties of supports and catalysts were characterized by N2 absorption-desorption
X-ray diffraction
SEM
TEM
Raman spectra and NH3-TPD. The effect of different loading of GO was investigated. The results showed that when the mass fraction of GO/TiO2(NF) was 0.5%
the intermediate-strong acid sites increased to the maximum. Under the mild conditions of 280℃
2.0 MPa
LHSV 4 h-1 and H2/feed ratio 400 (vol)
the corresponding catalyst exhibited the excellent HDS performance.
