催化剂广泛应用于石油精炼和化学工业中。在二次资源中,废催化剂无疑是非常重要的,不仅由于其量大且有巨大的经济价值,而且也由于其如果随意处置会对环境产生危害。废加氢脱硫催化剂通常由硫化钼组成,混合有铝基钒、钴和镍的硫化物。有多种冶金方法可以处理这些废催化剂,但都采 Catalysts are widely used in petroleum refining and chemical industries. In secondary resources, spent catalysts are undoubtedly important not only because of their large size and enormous economic value, but also because of their environmental impact if left untreated. Waste hydrodesulfurization catalysts are usually composed of molybdenum sulfide mixed with vanadium aluminum, cobalt and nickel sulfide. There are a variety of metallurgical processes that can handle these spent catalysts, but all are mining
