摘要: 采用渣油废催化剂为原料,考察了焙烧温度,液固比及pH等因素对金属回收率的影响;通过正交实验考察了原料配比、焙烧温度、焙烧时间、液固比及水浸时间对氧化铝转化率的影响,并采用N2物理吸附⁃脱附、XRD和SEM进行表征。结果表明,在焙烧温度800 ℃和液固比为5∶1时,钼和钒的浸出率可以达到94.0%以上;控制pH为1时,钼酸回收率可以达到97.6%;通过正交实验,确定了氧化铝回收条件:原料配比1.5,焙烧温度900 ℃,焙烧时间3 h,液固比5∶1,水浸时间15 min。

Abstract: The effects of calcination temperature,liquid⁃solid ratio and pH on metal recovery were investigated in this work.The influence of the ratio of raw materials, calcination temperature, calcination time,liquid⁃solid ratio and water immersion time on the conversion of alumina was investigated by orthogonal experiment,and characterized by N2 physical adsorption desorption,XRD and SEM.The results showed that 94.0% molybdenum and vanadium could be leached out with the calcination temperature of 800 ℃ and liquid⁃solid ratio of 5∶1.Furthermore,97.6% of the molybdenum ions could be recovered when the pH reached to 1. Through the orthogonal experiment,the recovery conditions of alumina were determined: the ratio of raw material to solid was 1.5,the calcination temperature was 900 ℃,the calcination time was 3 h,the ratio of liquid to solid was 5∶1,and the water immersion time was 15 min.
