摘要
以辽宁阜新煤矸石热电厂收集的不同粒度和组分粉煤灰样品为载体,铁铈氧化物混合物为活性组分,高岭土为粘结剂。经过机械混合,成型,干燥和高温煅烧,制备出柱状样品,在120℃条件下干燥4h,再700℃煅烧8h。制备了铁铈复合高温煤气脱硫剂,利用成分分析、X射线衍射和扫描电子显微镜等分析测试手段对制备的铁基高温脱硫剂及其载体进行了表征。结果表明以粉煤灰为载体的铁铈高温煤气脱硫剂在400-600oC温度范围内具有良好的硫化活性。
Using different size range of flying ash samples from gangue thermal power plant of Liaoning Fuxin as carrier, Fe-Ce oxide as active component, Kaolin as binder, through mechanical mixing, forming, drying and high temperature calcination, columnar samples are prepared. In the condition of 120℃, drying for 4h,then calcining in 700℃ for 8h, the iron-cerium-based sorbents for hot coal gas desulphurization were prepared using coal ash as the support and the sorbents and coal ash are characterized by means of numerous analytical methods such as composition analysis, XRD and SEM. The results clearly indicate that the sorbents prepared using coal ash as the support demonstrate high reactivity and high resistance to attrition during sulfidation during the temperature range of 400 ℃ to 600℃.
