摘要

Abstract

In this work MgO/Al

nanocomposites with weight ratios from 5% to 25% were synthesized by precipitationimpregnation method and their structural properties were characterized. In the next step

the capability of the nanocomposites in H

S removal compared to Mg-Al spinel (MgAl

)

synthesized through ion-pair complex precursor route and alumina samples

prepared

via

sol-gel precipitation methods

was investigated. The results indicated that among the studied sorbents Mg-Al spinel presents a distinctly higher H

S removal. In addition

the MgO/Al

nanocomposites compared to the alumina sorbents

exhibited much better performance in H

S removal. Also CO

-TPD analysis reveals higher amounts of basic sites for Mg-Al spinel compared to 25 wt% MgO/75 wt% Al

nanocomposite.
