氢型钛纳米管的制备及其在催化氧化脱硫中的应用
Preparation and Catalytic Oxidation Desulfurization of H-titanate Nanotube
摘要
Abstract
H-Titanate nanotube was synthesized through hydrothermal method and characterized by scanning electron mi-croscopy(SEM),transmission electron microscopy(TEM),and X-ray diffraction(XRD).The catalytic oxidative desulfuri-zation activity of H-TiNT was studied by using H2O2,as oxidant.The catalytic oxidative desulfurization performance of H-TiNT for four kinds of models of sulfur-containing compounds:dibenzothiophene(DBT),thiophene(Th),benzothiophene (BT)and 4,6-dimethyldibenzothiophene(4,6-DMDBT)were studied,and the effect of temperature,n(O)/n(S)and catalyst dosage were also investigated.The results showed that the effect of catalytic oxidation desulfurization activity of different sulfur compounds was as follows:DBT>BT>Th>4,6-DMDBT.Under the conditions of temperature of 40,℃,catalyst dosage 6.6,g/L and n(O)/n(S)=4,almost 100%, of DBT can be removed,and no activity loss was observed after the cata-lyst was used 5 recycles.关键词
