摘要

以传统固相烧结法制备的不稳定的层状K2Ti2O5为前驱体

直接将钛酸钾晶须进行离子交换得到具有纳微复合结构的TiO2载体

等体积浸渍法制备出MoO3/TiO2催化剂

运用SEM、XRD、BET、TEM等技术手段对载体和催化剂进行表征

并考察了该TiO2复合结构负载催化剂的加氢脱硫催化活性。SEM和XRD分析显示:该纳微米复合结构是由纳米颗粒与微米晶须构成的特殊结构

拥有不同形貌和尺寸的TiO2却具有相同的锐钛矿相。与单独TiO2纳米粒子和TiO2晶须相比

TiO2复合结构负载催化剂表现出更佳的脱硫催化能力

在温度310℃、压力2.1 MPa、体积空速6 h-1、氢/油体积比600条件下

催化剂表现出优异的DBT脱硫性能。

Abstract

With unstable layered K2Ti2O5 as the precursor in the traditional preparation of solid phase sintering

nano/micro-composite TiO2 (TiO2-m) derived from K2Ti2O5 was synthesized via ion-exchange. Supported MoO3/TiO2-m catalysts were prepared by incipient impregnation. Simultaneously

the properties of supports and catalysts were characterized by means of SEM

XRD

BET and TEM. An investigation into the HDS performance of MoO3/TiO2-m catalysts for dibenzothiophene was performed. SEM and XRD results showed that the prepared TiO2-m supports were shaped in nano-scale particle and micron-sized whisker morphology

having the same anatase phase with different morphologies and sizes of TiO2. Compared with pure morphology control sample

HDS tests indicated that Mo catalysts supported on TiO2-m showed the best HDS catalytic activity under relatively mild reaction conditions (310℃

2.1 MPa

LHSV 6 h-1 and H2/feed ratio 600 m3·m-3).
