摘要

以自制的大比表面介孔二氧化钛晶须作为加氢脱硫催化剂的载体

采用一步浸渍法制备了MoO3-NiO/TiO2催化剂

并用 X 射线衍射、N2 吸附-脱附、SEM、拉曼衍射等技术对载体和催化剂进行了表征

考察了TiO2晶须材料作为二苯并噻吩(DBT)上加氢脱硫(HDS)催化剂载体的性能及优越性

并详细考察了不同TiO2载体的晶型与比表面积对催化剂加氢脱硫反应活性的影响。结果表明

TiO2介孔晶须具有较为活泼的锐钛矿相和晶须形貌

同时提供了大的比表面积和特殊的孔道结构

在温度280℃、氢分压2.0 MPa、氢/油体积比400、体积空速4 h-1的温和条件下

DBT转化率即可接近100%。比表面积相近时

催化剂的脱硫效果依次为锐钛矿相>混晶>金红石相;同为锐钛矿相TiO2载体

催化剂的脱硫效果随着比表面的增大而增加。

Abstract

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.
