Role of TiO2 on Oxidative Regeneration of Spent High-Temperature Desulfurization Sorbent ZnO−TiO2

摘要: To develop an easily regenerable high-temperature desulfurization sorbent, the role of TiO2 in course oxidative regeneration ZnO−TiO2 presence O2 and H2O was studied. ZnO were prepared by a precipitation method using aqueous solutions Zn(NO3)2, Ti(SO4)2, sol, NH3. The character spent examined temperature-programmed reaction technique isotopic H218O. It found that accelerated both between ZnS also H2O. Furthermore, acceleration could be explained activation over spillover activated species.
