负载型氧化锌脱硫剂脱硫性能的改善
PERFORMANCE IMPROVEMENT OF THE SUPPORTED ZnO/γ-Al2O3 SORBENT
摘要
Abstract
As for the single zinc oxide loading type desulfurizer, desulfurization accuracy can reach 0. 1 X 10-6, but its sulfur capacity is relatively lower. In this study, the supported ZnO MnO2/y-Al2O3 sorbents were prepared by the impregnation method. The effect of MnO2 additive on phase, texture and specific surface area of Zn based sorbents were investigated by XRD and BET, respectively. The desulfurization performance was studied from Zn: Mn loading, sintering temperature and sulfidation temperature in a fixed bed reactor. The results revealed that H2S could be removed from 65 X 10~6 to less than 0.1×1CT6 and the largest sulfur content was 19. 08 g S/ 100 g (ZnOMn02) by the sorbent with 8: 1 mole ratio of Zn:Mn and 20% loading. The additive MnO2 phase can obviously enhanced the properties of single zinc oxide loading desulfurizer.关键词
