摘要
研究了石油化工废催化剂酸、碱、碱浸法制备氧化钒的工艺。根据实验结果选择了最有效的药剂、药剂用量、浸出时间和矿浆温度。以氢氧化钠溶液(200 g / l)为萃取剂，固液比T: l = 1:3，矿浆温度100°С，工艺时间约3小时，溶液中氧化钒提取率可达80%。
STUDY OF EFFECTIVE EXTRACTION OF VANADIUM OXIDE FROM SPENT PETROCHEMICAL CATALYSTS BY LEACHING METHOD
The process of acid, alkaline and soda leaching of spent petrochemical catalysts to produce vanadium oxide has been studied. The most effective reagent, its consumption, leaching duration and pulp temperature were chosen according to the results of the experiments. 80% extraction of vanadium oxide in the solution was achieved by using sodium hydroxide solution (200 g / l) as a reagent, solid-liquid phase ratio T:L = 1:3, pulp temperature 100 °С, process duration of about 3 hours.
