A nano-size zinc oxide sorbents was formulated for the effective removal of sulfur compounds (H2S) at a very low

concentration (under 50 ppmv) in a gasified fuel gas. They were prepared by a matrix-assisted method in this

study. An active carbon was used as a matrix and zinc acetate (Zn(C2H3O2)2 2H2O) was selected as a precursor.

About 10-40 wt% of zinc was doped over the activated carbon in the preparation of the sorbents. Content of the

zinc doped over the activated carbon had an influence on the morphology of zinc oxide nanostructure. The

reactivity tests of the ZnO nanostructures having various morphologies were performed in a fixed bed reactor.

Their reactivity increased as their sizes became smaller and their surface areas made larger. Most prepared nanosize

zinc oxides showed an excellent performance for the removal of H2S at a very low concentration.
