| 摘 要： | 脱硫剂中加入助剂不仅可以提高脱硫剂的耐久性和机械强度,还可以提高其化学稳定性.采用机械混合法制备了锰铜脱硫剂,通过XRD,SEM和BET等手段研究了助剂对脱硫剂的结构、物相及比表面积的影响.并在固定床反应器中考察了助剂对脱硫剂脱硫性能的影响.实验结果表明,活性组分锰铜摩尔比为9:1,黏结剂选用10%自制溶胶来代替矿物黏结剂制备得到的脱硫剂有较好的脱硫性能,脱硫精度最高可达8×10-6,硫容量可达33.1%.助剂的加入可以改善脱硫剂的脱硫性能.

| Abstract: | CT Manganese-based oxide as a high-temperature desulfurization sorbent was prepared with different additive by the mixing method and its performance was studied in a fixed bed reactor. The effect of additive on phase, texture and specific surface area of Mn-based sorbents were investigated by XRD, SEM and BET. The results reveal that H2S could be desulfured to 8×10~(-6) and desulfurization performance. The change of additive can effects the micro-structure and reactivity of the sorbents. |
