Abstract

Abstract:

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.

Key words: electro-spinning, TiO₂ nanofibers, graphene oxide, hydrodesulfurization, catalyst, support

摘要：

以静电纺丝法制备TiO₂纳米纤维(TiO₂(NF))和TiO₂-氧化石墨(GO)复合纳米纤维(TiO₂(NF)-GO)加氢脱硫催化剂的载体,采用等体积浸渍法制备NiMo/TiO₂(NF)和NiMo/TiO₂(NF)-GO催化剂,运用N₂吸附-脱附、X射线衍射、XPS、TEM、Raman光谱和NH₃程序升温脱附等表征手段对载体和催化剂进行表征分析,并考察掺杂不同含量GO对催化剂加氢脱硫性能的影响。实验结果表明,当GO/TiO₂(NF) 质量分数为0.5%时,复合载体的中强酸增加得最多,在温度280℃、氢气分压2.0 MPa、体积空速4 h^-1,氢油体积比400相当温和条件下,对应的催化剂表现出优异的加氢脱硫性能。
