文摘
- •
ZnO–Al2O3 mixed oxides were synthesized using a cation–anion double hydrolysis method.
- •
Mixed oxide based adsorbents exhibited high activity and large sulfur capacity in reactive adsorption desulfurization.
- •
The absence of the inactive NiAl2O4 phase in the adsorbents allowed the fast cleavage of C–S bond in thiophene.
- •
The high concentration of surface Lewis acid sites in mixed oxides favored the adsorption of thiophene.
- •
The high dispersion of ZnO in mixed oxides led to high diffusion rate of sulfur in ZnO particles.
