摘要：針對化工醫(yī)藥行業(yè)內(nèi)的高有機Pd/Al2O3廢催化劑，提出“無氧中溫熱解-充分氧化焚燒”Pd富集工藝。該工藝首先通過控制無氧中溫熱解氛圍，避免有機物在氧化氣氛下形成二噁英等有害物質(zhì)，然后利用充分氧化二次焙燒去處殘余積碳，達到高效富集Pd的同時降低對環(huán)境的影響。

Abstract： A Pd enrichment process of “oxygen-free medium-temperature pyrolysis-full oxidation incineration” is proposed for high organic Pd/Al2O3 waste catalysts in the chemical and pharmaceutical industries. This process first controls the anaerobic mesophilic pyrolysis atmosphere to avoid the formation of harmful substances such as dioxins in the oxidizing atmosphere of organic matter. Then， it utilizes sufficient oxidation and secondary roasting to remove residual carbon deposits， achieving efficient enrichment of Pd while reducing environmental impact.
