Study on Optimization of Enrichment Process for Pd/Al2O3 Waste Catalyst
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.
