摘要
Abstract
To address the challenge of recovering spent catalysts supported on Al2O3 with high SiO2 content,an"alkali leaching+weak acid leaching"enrichment process is proposed.By optimizing parameters such as alkali dosage,leaching temperature,hydrochloric acid concentration,and liquid-to-solid ratio,this process achieves efficient Pt and Pd enrichment while preventing Si from entering the leachate.关键词
