ABSTRACT:
A process for the recovery of cobalt and manganese from solid aromatic acid oxidation incinerator ash, pyrolysis sand and pyrolysis char is disclosed. The process comprises heating the solid residue at a temperature of about 120.degree. to about 300.degree. C. and a pressure of about 3 atmospheres to about 30 atmospheres. The recovered catalyst is useful for the oxidation of alkyl aromatic hydrocarbons to their corresponding di- or tricarboxylic acids which are used for the manufacture of fibers, films and molded products.
