中文摘要: 针对V2O5含量16.3%、Mo含量2.02%的HDS渣开展综合回收利用钒、钼的研究。结果表明，优选试验条件为：350 ℃脱油1 h，HDS渣粒度-212 μm百分含量≥96%，750 ℃脱碳脱硫2 h，碳酸钠添加量与钒钼含量的摩尔比为1.2，800 ℃焙烧2 h，浸出液固比2︰1，浸出温度40 ℃，浸出时间30 min。钒浸出率为94.76%，钼浸出率为96.93%。可为含钒废催化剂的综合回收利用提供参考。
Abstract:Comprehensive recycling of V and Mo from HDS slag, which contains V2O5 16.3%, Mo 2.02%, was studied. The results show that leaching rate of V and Mo is 94.76% and 96.93% respectively under the optimum conditions including deoiling at 350 ℃ for one hour, particle size of waste catalyst of -212 μm of ≥96%, decarburization and desulfurization at 750 ℃ for two hours; molar ratio of sodium carbonate to vanadium and molybdenum content of 1.2, calcination at 800 ℃ for 2 h, L/S of 2︰1, leaching temperature of 40 ℃, and leaching time of 30 min. It can provide reference for comprehensive recovery and utilization of vanadium-containing waste catalyst.
