摘　　要：针对蒽醌降解物再生原理,选择适宜的活性组分,以氧化铝为载体负载活性组分,制备新型复合氧化铝再生剂(命名为SX-301),以提高再生剂的活性及使用周期。实验在吉林双欧化工有限公司3.5万t/a双氧水(质量分数为27.5%)工业装置上进行,考核新型氧化铝再生剂在实际生产中的综合性能。结果显示:新型氧化铝再生剂使用后不影响氢效、氧效和吸碱效果,蒽醌降解物再生效果明显,再生剂使用周期长。新型氧化铝再生剂使用两个月后,有效蒽醌质量浓度从147 g/L增长到166 g/L,在此期间未补加蒽醌,新型氧化铝再生剂显示出良好的再生活性。According to the principle of anthraquinone degradation material regeneration,a new composite alumina regenerant(named SX-301)was prepared with alumina loading active composition to improve its activity and service life.The experiment was carried out on a35000t/a industrial hydrogen peroxide(mass fraction of27.5%)plant to evaluate the comprehensive per formance of the new alumina regenerant in actual production.The results showed that the regenerant did not affect the hydro genation efficiency,oxidation efficiency and alkali absorption efficiency.The regeneration effect of anthraquinone degradation was obvious and the alumina regenerant exhibited an excellent stability.The effective anthraquinone was increased from147g/L to166g/L after two months.During this period,anthraquinone was not added,which indicated a good regeneration activity.
