设计并建立了一条以高湍流反应塔为核心设备的废铜铋催化剂再生工艺生产线,从工业化的角度研究了废旧铜铋催化剂的再生回收可行性,并且通过工业化运行经验证明了该工艺的可行性。运行情况表明,该系统的再生催化剂回收率为98.9%,再生催化剂与新鲜的催化剂颗粒粒径基本一致,组分含量相似,仍保留79.45%~81.50%的催化活性,在使用特性上具有一般替代性。运行经济性分析表明,系统低负荷时运行成本仍处于较高水平,额定投料量下运行综合效益最高,在该负荷下运行每年预计可为企业综合提升效益约2 255万元。

A spent copper-bismuth catalyst regeneration process production line is designed and established,which employs a high turbulence reaction tower as the core equipment.The feasibility of regeneration and recycling of spent copper-bismuth catalyst is studied from the perspective of industrialization,and is proved through industrial operation experiences.The operation situation shows that the recovery rate of regenerated catalyst by the system reaches 98.9%.The regenerated catalyst has the nearly same particle size as the fresh catalyst does.They have the similar component content.The regenerated catalyst retains 79.45%-81.50% of catalytic activity,and possesses general substitution for the fresh one in the using characteristics.It is found through the operation economic analysis that the system delivers a high level of operational cost when it runs at a low load,while the highest comprehensive benefit can be gained at the designed load,under which the comprehensive benefit can be increased by about RMB22.55 million per year.
