Research on Reactive Adsorption Desulfurization Over Metal Oxides Adsorbent

Reactive adsorption desulfurization over metal oxides adsorbents was carried out to remove the sulfur of real fluid catalytic cracking gasoline and model gasoline in a batch reactor at low pressures in the presence of hydrogen. The results show that Ni appearing after reduction and higher temperature leads to a significant improvement in the desulfurization ability of the adsorbents. When the initial concentration of thiophene in the model gasoline raised the sulfur, removal rate decreased while the adsorption capacity of the adsorbents increased and the maximum sulfur removal rate and sulfur adsorption capacity were 86.33% and 13.72 mg/g, respectively.
