VERFAHREN ZUR RÜCKGEWINNUNG VON KATALYSOR- ÜBERGANGSMETALLEN AUS SALZHALTIGEN REAKTIONSGEMISCHEN |
摘要 |
<p>Transition metals may be recovered from a salt-containing mixture containing at least one transition metal compound, salts, and organic compounds by separating from the salt-containing mixture a mixture of the transition metal compound and the salts. This mixture, together with any organic impurities, is introduced into a combustion zone, and the flue gas/salt mixture leaving the combustion zone is quenched with water. The combustion residue, containing the transition metal, is separated from the resulting quench solution, dried, and converted to fresh catalyst.</p> |
