摘要
文章根据废催化剂氯化锌沉淀物的特征,通过实验验证,氨水洗涤,脱除Cl-、SO42-,并大幅度降低Zn(OH)2沉淀物体积,再经过焙烧,可研制出合格的饲料添加剂氧化锌或者活性氧化锌。
According to the feature of precipitate of zinc chloride in spent catalyst, and Various experiments; washing with a small amount of Ammonia; removing chloride and Sulfate ions; reducing sediment volume of Zn(OH)2 by a large margin and after roasting, Zinc oxide feed additives and active zinc oxide that meet the standards would be developed.
