An attempt using self-regulating mesoporous titanium dioxide whisker as catalyst carrier of hydrogen desulfurization
was carried out to prepare MoO3-NiO/TiO2 catalyst by single-step incipient wetness impregnation.X-ray
N2 absorption/desorption
SEM
Raman diffraction were adopted to characterize the carrier and catalyst.The effect of mesoporous TiO2 whisker as catalyst carrier on the performance of dibenzothiophene (DBT)hydrogen desulfurization (HDS)was evaluated.The results showed that the mesoporous TiO2 whisker had highly active anatase
whisker morphology and larger specific surface area as well as special pore structure.DBT conversion over mesoporous TiO2 whisker could approach 100% under moderate conditions of reaction temperature 280℃
hydrogen partial pressure 2.0 MPa
hydrogen/oil volume ratio 400 and LHSV 4 h-1.Under the condition of similar specific surface area
the sequence of the desulfurization effect of the tested catalysts was anatase> mixed crystals of TiO2 >rutile.As anatase carriers are concerned
the desulfurization effect increased with the increase of the specific surface area of TiO2 carrier.
